The Formation of Dwarf Galaxy Disks
Robel Geda, Akaxia Cruz, Anna C. Wright +5
Dwarf galaxies are dark matter-dominated systems that are sensitive to feedback and display a diversity of baryonic morphologies. This makes them excellent probes for understanding…
MARVELously Dark: the density profile evolution of dwarf halos in velocity-dependent SIDM
Anna Engelhardt, Ferah Munshi, Annika H. G. Peter +6
Self-interacting dark matter (SIDM) with a sufficiently large cross section has been shown to naturally produce constant dark matter (DM) cores, as well as core-collapse, at the ce…
The Simulated Oxygen Shortage (SOS): Mapping the Missing OVI in Simulated Dwarf Galaxies to Subgrid Physics
Daniel R. Piacitelli, Alyson M. Brooks, N. Nicole Sanchez +9
Observations reveal extended \OVI\, reservoirs in the circumgalactic medium (CGM) of dwarf galaxies, yet current simulations systematically underpredict \OVI\, column densities. Ut…
Trends with Mass for Dwarf Galaxies from the Marvelous Massive Dwarfs Suite
Dilys Ruan, Alyson M. Brooks, Leonardo A. Barba +7
Galaxy formation scenarios can be interpreted through galaxy morphology and the level of rotational versus pressure support, quantified through the ratio of a galaxy's rotation spe…
CASCO: Cosmological and AStrophysical parameters from Cosmological simulations and Observations IV. Testing warm dark matter cosmologies with galaxy scaling relations: A joint simulation-observation study using DREAMS simulations
M. Silvestrini, C. Tortora, V. Busillo +9
Small-scale discrepancies in the standard Lambda cold dark matter paradigm have motivated the exploration of alternative dark matter (DM) models, such as warm dark matter (WDM). We…
The Merian Survey: A Statistical Census of Bright Satellites of Milky Way Analogs
Yue Pan, Shany Danieli, Jenny E. Greene +10
We present a statistical census of bright, star-forming satellite galaxies around Milky Way (MW) analogs using the first data release of the Merian Survey. Our sample consists of 3…
