The Distribution Of Ultra-Diffuse And Ultra-Compact Galaxies In The Frontier Fields, Steven Janssens, Roberto Abraham, Jean Brodie, Duncan Forbes, Aaron Romanowsky Dec 2019

The Distribution Of Ultra-Diffuse And Ultra-Compact Galaxies In The Frontier Fields, Steven Janssens, Roberto Abraham, Jean Brodie, Duncan Forbes, Aaron Romanowsky

Faculty Publications

Large low-surface-brightness galaxies have recently been found to be abundant in nearby galaxy clusters. In this paper, we investigate these ultra-diffuse galaxies (UDGs) in the six Hubble Frontier Fields galaxy clusters: A2744, MACS J0416.1−2403, MACS J0717.5+3745, MACS J1149.5+2223, AS1063, and A370. These are the most massive (1–3 × 1015 M ⊙) and distant (0.308 < z < 0.545) systems in which this class of galaxy has yet been discovered. We estimate that the clusters host of the order of ~200–1400 UDGs inside the virial radius (R 200), consistent with the UDG abundance–halo-mass relation found in the local universe, and suggest that UDGs may be formed in clusters. Within each cluster, however, we find that UDGs are not evenly distributed. Instead their projected spatial distributions are lopsided, and they are deficient in the regions of highest mass density as traced by gravitational lensing. While the deficiency of UDGs in central regions is not surprising, the lopsidedness is puzzling. The UDGs, and their lopsided spatial distributions, may be associated with known substructures late in their infall into the clusters, meaning that we find evidence both for formation of UDGs in clusters and for UDGs falling into clusters. We also investigate the ultra-compact dwarfs (UCDs) residing in the clusters, and find that the spatial distributions of UDGs and UCDs appear anticorrelated. Around 15% of UDGs exhibit either compact nuclei or nearby point sources. Taken together, these observations provide additional evidence for a picture in which at least some UDGs are destroyed in dense cluster environments and leave behind a residue of UCDs.

Use Of Mobile Phones In Scholarly Publications: A Review Of The Emerging Behaviour Of The 21st Century Scholars, Sudhier K G Pillai Dr.

Library Philosophy and Practice (e-journal)

Scholars engage in intellectual enquiries which is why they are considered to be the cornerstones of any research geared towards solving societal problems or testing phenomena. This makes their research outputs needed to be readily available for public consumption. For quite long, scholars are rated based on the number of scholarly contributions they make. While mobile phone has diffused, adopted and used as part of our everyday life, researchers neglected the dimensions of attitudes of scholars for adopting and use of mobile phone technology in the course of their scholarly communication. The components of attitudes of scholars for adopting and …

Image-Based Localization Of User-Interfaces, Riti Gupta Dec 2019

Image-Based Localization Of User-Interfaces, Riti Gupta

Master's Projects

Image localization corresponds to translating the text present in the images from one language to other language. The aim of the project is to develop a methodology to translate the text in image captions from English to Hindi by taking context of the images into account. A lot of work has been done in this field [22], but our aim was to explore if the accuracy can be further improved by consideration of the additional information imparted by the images apart from the text. We have explored Deep Learning using neural networks for this project. In particular, Recurrent Neural Networks …

Music Retrieval System Using Query-By-Humming, Parth Patel Dec 2019

Music Retrieval System Using Query-By-Humming, Parth Patel

Master's Projects

Music Information Retrieval (MIR) is a particular research area of great interest because there are various strategies to retrieve music. To retrieve music, it is important to find a similarity between the input query and the matching music. Several solutions have been proposed that are currently being used in the application domain(s) such as Query- by-Example (QBE) which takes a sample of an audio recording playing in the background and retrieves the result. However, there is no efficient approach to solve this problem in a Query-by-Humming (QBH) application. In a Query-by-Humming application, the aim is to retrieve music that is …

A Hybrid Approach For Multi-Document Text Summarization, Rashmi Varma Dec 2019

A Hybrid Approach For Multi-Document Text Summarization, Rashmi Varma

Master's Projects

Text summarization has been a long studied topic in the field of natural language processing. There have been various approaches for both extractive text summarization as well as abstractive text summarization. Summarizing texts for a single document is a methodical task. But summarizing multiple documents poses as a greater challenge. This thesis explores the application of Latent Semantic Analysis, Text-Rank, Lex-Rank and Reduction algorithms for single document text summarization and compares it with the proposed approach of creating a hybrid system combining each of the above algorithms, individually, with Restricted Boltzmann Machines for multi-document text summarization and analyzing how all …

3d Shape Prediction On Convolutional Deep Belief Networks, Gregory Y. Enriquez Dec 2019

3d Shape Prediction On Convolutional Deep Belief Networks, Gregory Y. Enriquez

Master's Projects

The field of image recognition software has grown immensely in recent years with the emergence of new deep learning techniques. Deep belief networks inspired by Hinton [11] were one of the earliest methodologies of deep learning in the late 2000s. More recently, convolutional neural networks have been used in deep learning techniques, architecture, and software to identify patterns in imagery in order to make predictions such as classification, image segmentation, etc. Traditional two-dimensional, or 2D, images stored as picture files, typically contain red, green, and blue color data for each individual pixel in the picture. However, more recent commercial 2.5D …

Mission-Driven Recordkeeping: The Need For Rim Staff In U.S. Nonprofit Organizations, Emily Mercer Dec 2019

Mission-Driven Recordkeeping: The Need For Rim Staff In U.S. Nonprofit Organizations, Emily Mercer

School of Information Student Research Journal

As a robust and growing industry, often with strong ties to communities served, there is much potential for nonprofit organizations to harness powerful and rich databases of cultural information not found in any other sector. Yet research shows that in most cases, nonprofit organizations operate on limited budgets, tight deadlines, and may see the task of properly managing records as counter-productive to the mission of the organization. This research examines the systems of recordkeeping in nonprofit organizations in the U.S. and argues that record keeping staff must be considered an essential component for a nonprofit organization to survive and thrive.

Genealogical Plagiarism And The Library Community, Katherine S. Richers Dec 2019

Genealogical Plagiarism And The Library Community, Katherine S. Richers

School of Information Student Research Journal

Plagiarism is regarded as an academic crime, but can affect hobbies that rely on research and information sharing such as genealogy. The issue is well-known within the genealogy community. However, information professionals who aid genealogists in their research may not know enough about the issue. How can the library field respond constructively to the issue of uncontrolled plagiarism in genealogy? While the genealogy community condemns plagiarism and offers resources to correct it, current library practices concentrate on services and not on plagiarism education in the genealogy context, concentrating more on copyright and legal problems. The library field can help professionals …

The Information Behaviors Of Fiction Writers: A Systematic Approach To An Understudied Information Community, Lisa Lowdermilk Dec 2019

The Information Behaviors Of Fiction Writers: A Systematic Approach To An Understudied Information Community, Lisa Lowdermilk

School of Information Student Research Journal

Within the context of creative information communities in general, fiction writers remain a relatively understudied community. This article seeks to rectify that gap by highlighting the information behaviors of fiction writers, including the ways in which they network, as well as the processes they use when writing. In doing so, it reveals that fiction writers of all genres have many experiences in common, such as the "seed incident" that serves as the starting point when writing fiction. In addition, it examines fiction writers' impact on readers, with the implication that everyone--writers and non-writers alike--would benefit from understanding fiction writers' information …
