Mergers Matter: Gravothermal Collapse in Dwarf Halos with Self-Interacting Dark Matter
Maya Silverman, Abdelaziz Hussein, Arpit Arora +8
Self-Interacting Dark Matter (SIDM) models with large cross sections at relative velocities below can be tested with dwarf galaxy observations. We ana…
WeatherOcc3D: VLM-Assisted Adverse Weather Aware 3D Semantic Occupancy Prediction
A. Enes Doruk, Abdelaziz Hussein, Hasan F. Ates
While multi-modal 3D semantic occupancy prediction typically enhances robustness by fusing camera and LiDAR inputs, its effectiveness is fundamentally constrained by environmental…
Formation and Redshift Evolution of Dark Matter Spikes
Gonzalo Herrera, Abdelaziz Hussein, Lina Necib +2
Dark matter density spikes forming around adiabatically growing black holes can dramatically enhance indirect and direct detection signals. Canonical predictions, however, assume a…
The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles
Alex M. Garcia, Jonah C. Rose, Paul Torrey +23
In this work, we utilize a new suite of Milky Way-mass halos from the DREAMS Project, simulated with Cold Dark Matter (CDM), to quantify the influence of baryon feedback and intrin…
The Shape of FIREbox Galaxies and a Potential Tension with Low-mass Disks
Courtney Klein, Jenny D. Wang, Luke Xia +9
We study the intrinsic and observable shapes of approximately 700 star-forming galaxies with stellar masses of M from the FIREbox simulation at . We c…
Dark Matter-Electron Interactions Alter the Luminosity and Spectral Index of M87
Abdelaziz Hussein, Gonzalo Herrera
We investigate the possibility that cosmic-ray electron cooling through dark matter-electron scatterings contributes to the low radiative efficiency observed in radio-loud galaxies…
