The Velocity-Dependent -factor of the Milky Way Halo: Does What Happens in the Galactic Bulge Stay in the Galactic Bulge?
Kenny Kiriu, Jason Kumar, Jack Runburg
We consider the angular distribution of the photon signal which could arise from velocity-dependent dark matter annihilation within the Galactic bulge. We find that, for the case o…
Searching for velocity-dependent dark matter annihilation signals from extragalactic halos
Eric J. Baxter, Jason Kumar, Aleczander D. Paul +1
We consider gamma-ray signals of dark matter annihilation in extragalactic halos in the case where dark matter annihilates from a -wave or -wave state. In these scenarios, si…
Stellar and black hole assembly in z<0.3 infrared-luminous mergers: intermittent starbursts vs. super-Eddington accretion
Duncan Farrah, Andreas Efstathiou, Jose Afonso +20
We study stellar and black hole mass assembly in a sample of 42 infrared-luminous galaxy mergers at z<0.3 by combining results from radiative transfer modelling with archival measu…
Sensitivity to Dark Sector Scales from Gravitational Wave Signatures
James B. Dent, Bhaskar Dutta, Sumit Ghosh +2
We consider gravitational wave signals produced by a first-order phase transition in a theory with a generic renormalizable thermal effective potential of power law form. We find t…
Consistent analysis of the AGN LF in X-ray and MIR in the XMM-LSS field
Jack Runburg, Duncan Farrah, Anna Sajina +9
The luminosity function (LF) of active galactic nuclei (AGN) probes the history of supermassive black hole assembly and growth across cosmic time. To mitigate selection biases, we…
-factors for Velocity-dependent Dark Matter
Bradly Boucher, Jason Kumar, Van B. Le +1
If dark matter annihilates with a velocity-dependent cross section within a subhalo, then the magnitude and angular distribution of the resulting photon signal will change. These e…
Constraining Dark Matter Microphysics with the Annihilation Signal from Subhalos
Jack Runburg, Eric J. Baxter, Jason Kumar
In the cold dark matter scenario, galactic dark matter halos are populated with a large number of smaller subhalos. Previous work has shown that dark matter annihilations in subhal…
Prospects for measuring dark matter microphysics with observations of dwarf spheroidal galaxies
Eric J. Baxter, Jason Kumar, Andrew B. Pace +1
Dark matter annihilation in dwarf spheroidal (dSph) galaxies near the Milky Way has the potential to produce a detectable signature in gamma-rays. The amplitude of this signal depe…
Effective -factors for Milky Way dwarf spheroidal galaxies with velocity-dependent annihilation
Kimberly K. Boddy, Jason Kumar, Andrew B. Pace +2
We calculate the effective -factors, which determine the strength of indirect detection signals from dark matter annihilation, for 25 dwarf spheroidal galaxies (dSphs). We consi…
Angular distribution of gamma-ray emission from velocity-dependent dark matter annihilation in subhalos
Kimberly K. Boddy, Jason Kumar, Jack Runburg +1
We consider the effect of velocity-dependent dark matter annihilation on the angular distribution of gamma rays produced in dark matter subhalos. We assume that the dark matter pot…
