Dark Matter As An Integral Part Of An Alternative Gravity Model, Hontas Farmer
Dark Matter As An Integral Part Of An Alternative Gravity Model, Hontas Farmer
Hontas F Farmer
The purpose of this paper is to reconcile observations of dark matter effects on the galactic and cosmological scales with the null results of astroparticle physics observations such as CDMS and ANTARES. This paper will also provide a candidate unified and simpler mathematical formulation for the Lambda CDM model. Unification is achieved by a combination of the f(R) approach, with the standard LCDM approach and inflationary models. It is postulated that dark matter-energy fields depend on the Ricci curvature R. Standard methods of classical and quantum field theory on curved space time are applied. When this model is treated as …
Disk-Outflow Models As Applied To High Mass Star Forming Regions Through Methanol And Water Maser Observations, Hontas Farmer
Disk-Outflow Models As Applied To High Mass Star Forming Regions Through Methanol And Water Maser Observations, Hontas Farmer
Hontas F Farmer
As the recent publication by Breen et al (2013) found Class II methanol masers are exclusively associated with high mass star forming regions. Based on the positions of the Class I and II methanol and H2O masers, UC H~II regions and 4.5~μm infrared sources, and the center velocities (vLSR) of the Class I methanol and H2O masers, compared to the vLSR of the Class II methanol masers, we propose three disk-outflow models that may be traced by methanol masers. In all three models, we have located the Class II methanol maser near the protostar, and the Class I methanol maser …

Discovery Of A Massive Young Stellar Object In G10.47+0.27 By Way Of Meta Analysis Of Previously Published Data., Hontas F. Farmer
Discovery Of A Massive Young Stellar Object In G10.47+0.27 By Way Of Meta Analysis Of Previously Published Data., Hontas F. Farmer
Hontas F Farmer
We report the finding of a previously unidentified candidate massive young stellar object at the precise coordinates right ascension 18 08 38.2 and declination -19 51 50 in the region G10.47+0.27. This object was found by correlation of previously published data. At these coordinates the following key tracers of massive star formation are in a compact area; 4.5 micrometer infrared, a Class II methanol maser, two ionized hydrogen regions and three water masers. We also present a physical model of the disk and outflow in this region based on the morphology and kinematics of the methanol and water masers. Perhaps …
Massive Star Forming Cores And Outflows Found By Analysis Of Astronomical Data, Hontas Farmer
Massive Star Forming Cores And Outflows Found By Analysis Of Astronomical Data, Hontas Farmer
Hontas F Farmer
Like gems hidden in mountains of sand, I have sifted through vast amounts of data which have been gathered by surveys covering wide areas of the sky at particular wavelengths, and found likely star forming cores, hints of circumstellar disk and outflows in regions of massive star formation. The procedural lesson from my masters thesis is that there are discoveries waiting to be made by comparing data sets gathered at different frequencies, and by conducting coordinated multi-spectral surveys of massive star forming regions.

Insights Into High Mass Star Formation From Methanol Maser Observations., Hontas Freeman Farmer
Hontas F Farmer
We present high angular resolution data on Class I and Class II methanol masers, together with other tracers of star formation like H2O masers, ultracompact (UC) ionized hydrogen (H II) regions, and 4.5 μm infrared sources, taken from the literature. The aim is to study what these data tell us about the process of high mass star formation; in particular, whether disk-outflow systems are compatible with the morphology exhibited by Class I and Class II methanol masers. Stars form in the dense cores inside molecular clouds, and while the process of the formation of stars like our Sun is reasonably …
A Lagrangian Which Mathematically Models Lambda Cdm Cosmology And Explains The Null Results Of Dark Astroparticle Searches., Hontas Farmer
A Lagrangian Which Mathematically Models Lambda Cdm Cosmology And Explains The Null Results Of Dark Astroparticle Searches., Hontas Farmer
Hontas F Farmer
Background: The Lambda CDM model or is the standard model of modern cosmology. It is named for dark energy and cold dark matter. This model contains a number of separate components with different mathematical formulations. Strong observational evidence for dark matter has been found by astronomy. At the same time astroparticle physics observations have not found solid evidence of dark matter. Purpose: The purpose of this paper is to reconcile observations of dark matter effects on the galactic and cosmological scales with the null results of astroparticle physics observations such as CDMS and ANTARES. This paper will also provide a …
