Disentangling the Hadronic Components in NGC 1068
Marco Ajello, Kohta Murase, Alex McDaniel
The recent detection of high-energy neutrinos by IceCube in the direction of the nearby Seyfert/starburst galaxy NGC 1068 implies that radio-quiet active galactic nuclei can accele…
Cool Cores in Clusters of Galaxies in the Dark Energy Survey
K. Graham, J. O'Donnell, M. M. Silverstein +54
We search for the presence of cool cores in optically-selected galaxy clusters from the Dark Energy Survey (DES) and investigate their prevalence as a function of redshift and clus…
Simultaneous Millimeter-wave, Gamma-ray, and Optical Monitoring of the Blazar PKS 2326-502 During a Flaring State
J. C. Hood, A. Simpson, A. McDaniel +66
Including millimeter-wave (mm-wave) data in multi-wavelength studies of the variability of active galactic nuclei (AGN) can provide insights into AGN physics that are not easily ac…
Gamma-ray Emission from Galaxies Hosting Molecular Outflows
Alex McDaniel, Marco Ajello, Chris Karwin
Many star-forming galaxies and those hosting active galactic nuclei (AGN) show evidence of massive outflows of material in a variety of phases including ionized, neutral atomic, an…
Velocity Dispersions of Clusters in the Dark Energy Survey Y3 redMaPPer Catalog
V. Wetzell, T. E. Jeltema, B. Hegland +96
We measure the velocity dispersions of clusters of galaxies selected by the redMaPPer algorithm in the first three years of data from the Dark Energy Survey (DES), allowing us to p…
Cosmic-ray transport and gamma-ray emission in M31
Audrey Do, Matthew Duong, Alex McDaniel +5
We study the possibility that an extended cosmic-ray leptonic and/or hadronic halo is at the origin of the large-scale gamma-ray emission detected from the Andromeda Galaxy (M31).…
Exploring A Cosmic-Ray Origin of the Multi-wavelength Emission in M31
Alex McDaniel, Tesla Jeltema, Stefano Profumo
A recent detection of spatially extended gamma-ray emission in the central region of the Andromeda galaxy (M31) has led to several possible explanations being put forth, including…
A Multi-Wavelength Analysis of Annihilating Dark Matter as the Origin of the Gamma-Ray Emission from M31
Alex McDaniel, Tesla Jeltema, Stefano Profumo
[Abridged] Indirect detection of dark matter (DM) by multi-wavelength astronomical observations provides a promising avenue for probing the particle nature of DM. In the case of DM…
Multiwavelength Analysis of Dark Matter Annihilation and RX-DMFIT
Alex McDaniel, Tesla Jeltema, Stefano Profumo +1
Dark matter (DM) particles are predicted by several well motivated models to yield Standard Model particles through self-annihilation that can potentially be detected by astrophysi…
The Missing Link: Early Methane ("T") Dwarfs in the Sloan Digital Sky Survey
S. K. Leggett, T. R. Geballe, Xiaohui Fan
We report the discovery of three cool brown dwarfs which fall in the effective temperature gap between the latest L dwarfs currently known, with no methane absorption bands in the…
