Assessing the Impact of Hydrogen Absorption on the Characteristics of the Galactic Center Excess
Martin Pohl, Oscar Macias, Phaedra Coleman +1
We present a new reconstruction of the distribution of atomic hydrogen in the inner Galaxy that is based on explicit radiation-transport modelling of line and continuum emission an…
Snowmass2021 Cosmic Frontier White Paper: Puzzling Excesses in Dark Matter Searches and How to Resolve Them
Rebecca K. Leane, Seodong Shin, Liang Yang +36
Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Ast…
Snowmass2021 Cosmic Frontier: Synergies between dark matter searches and multiwavelength/multimessenger astrophysics
Shin'ichiro Ando, Sebastian Baum, Michael Boylan-Kolchin +23
This whitepaper focuses on the astrophysical systematics which are encountered in dark matter searches. Oftentimes in indirect and also in direct dark matter searches, astrophysica…
Measuring the smearing of the Galactic 511 keV signal: positron propagation or supernova kicks?
Thomas Siegert, Roland M. Crocker, Oscar Macias +4
We use 15 years of -ray data from INTEGRAL/SPI in a refined investigation of the morphology of the Galactic bulge positron annihilation signal. Our spatial analysis confirms tha…
Cherenkov Telescope Array sensitivity to the putative millisecond pulsar population responsible for the Galactic center excess
Oscar Macias, Harm van Leijen, Deheng Song +3
The leading explanation of the Galactic center -ray excess is the extended emission from a unresolved population of millisecond pulsars (MSPs) in the Galactic b…
Evidence for a high-energy tail in the gamma-ray spectra of globular clusters
Deheng Song, Oscar Macias, Shunsaku Horiuchi +2
Millisecond pulsars are very likely the main source of gamma-ray emission from globular clusters. However, the relative contributions of two separate emission processes--curvature…
