An Optically Motivated Gamma-ray Study of Fermi-LAT Novae
Owen K. Henry, Timothy A. D. Paglione, David Zurek +1
High-energy (GeV) gamma-ray emission from nova eruptions was a surprise detection by the Fermi-LAT in 2010. Since then, it has been suggested that the gamma-rays from these systems…
A Gamma-ray Stacking Survey of Fermi-LAT Undetected Globular Clusters
Owen K. Henry, Timothy A. D. Paglione, Yuzhe Song +3
We present evidence for -ray emission from a stacked population of 39 high-latitude globular clusters (GCs) not detected in the Fermi Point Source Catalog, likely attributable t…
Binary population synthesis of the Galactic canonical pulsar population
Yuzhe Song, Simon Stevenson, Debatri Chattopadhyay +2
Pulsars are rapidly rotating neutron stars that emit radiation across the electromagnetic spectrum, from radio to gamma-rays. We use the rapid binary population synthesis suite COM…
Searching For Gamma-ray Emission from Stellar Flares
Yuzhe Song, Timothy A. D. Paglione, Ekaterina Ilin
Flares from magnetically active dwarf stars should produce relativistic particles capable of creating gamma-rays. So far, the only isolated main sequence star besides the Sun to ha…
A Stacking Survey of Gamma-ray Pulsars
Yuzhe Song, Timothy A. D. Paglione, Joshua Tan +2
We report on a likelihood stacking search for gamma-ray pulsars at 362 high-latitude locations that coincide with known radio pulsar positions. We observe a stacked signal conserva…
A Stacking Search for Gamma-ray Emission from Nearby Flare Stars and the Periodic Source TVLM 513-46546
Yuzhe Song, Timothy A. D. Paglione
So far, the Sun is the only isolated main sequence star detected in gamma-rays, particularly during powerful flares. Young ultracool dwarfs are far more active so they are also pla…
Ultrahigh-Energy Cosmic Ray Composition from the Distribution of Arrival Directions
Rita C. dos Anjos, Jorge F. Soriano, Luis A. Anchordoqui +8
The sources of ultrahigh-energy cosmic rays (UHECRs) have been difficult to catch. It was recently pointed out that while sources of UHECR protons exhibit anisotropy patterns that…
Calibrating Column Density Tracers with Gamma-ray Observations of the Ophiuchi Molecular Cloud
Ryan D. Abrahams, Alex Teachey, Timothy A. D. Paglione
Diffuse gamma-ray emission from interstellar clouds results largely from cosmic ray (CR) proton collisions with ambient gas, regardless of the gas state, temperature, or dust prope…
High Latitude, Translucent Molecular Clouds as Probes of Local Cosmic Rays
R. D. Abrahams, T. A. D. Paglione
We analyze the gamma-ray emission from 9 high latitude, translucent molecular clouds taken with the Fermi Large Area Telescope (LAT) between 250 MeV and 10 GeV. Observations of gam…
Properties of Nearby Starburst Galaxies Based on their Diffuse Gamma-ray Emission
T. A. D. Paglione, R. D. Abrahams
The physical relationship between the far-infrared and radio fluxes of star forming galaxies has yet to be definitively determined. The favored interpretation, the "calorimeter mod…
