Reverberation Mapping Of Markarian 421 Using V,R, I, And Ha Filters, Alex Whitman
Reverberation Mapping Of Markarian 421 Using V,R, I, And Ha Filters, Alex Whitman
Honors Program Theses and Projects
Active Galactic Nuclei (AGN) at their most basic level are supermassive blackholes that emit light. While that sounds paradoxical, it speaks volumes to how little we know about these extraordinary objects. One technique that can be used, and was used here to better understand these objects is reverberation mapping. We employed this method on the AGN Markarian 421 (Mrk 421) at Bridgewater State University (BSU). Mrk 421 was chosen because it is the brightest known AGN, averaging 12.7 magnitudes, and the observational abilities of BSU are best suited for objects brighter than 18 magnitudes in optical wavelengths. We observed Mrk …

TeVJ2032+4130 is a high energy celestial object that emits Very High Energy (VHE) gamma rays and is located in the star forming region of the Cygnus constellation. It was first detected by the High Energy Gamma Ray Astronomy (HEGRA) experiment. Later observations from the Very Energetic Radiation Imaging Telescope Array System (VERITAS2014) were used to determine that the gamma-ray emission from the source could be coming from a Pulsar Wind Nebula (PWN) powered by a binary pulsar named PSR J2032+4127. For the PWN scenario, VERITAS predicted a cutoff in the gamma-ray spectrum above 10 TeV. Using ~33 hours of VERITAS …
