The Missing Black Hole in the Large Magellanic Cloud: A Dynamical Prediction for Its Present-Day Location
Robin Chisholm, Elena D'Onghia, Niv Drory +2
There are indications that the Large Magellanic Cloud (LMC) hosts a central supermassive black hole (SMBH), yet no direct detection exists: one reason is that its present-day locat…
The LMC Corona Favors a First Passage
Scott Lucchini, Jiwon Jesse Han, Sapna Mishra +1
We use constrained idealized simulations of the LMC/Milky Way interaction to determine if the size of the LMC's gaseous halo (Corona) can be used to distinguish between first and s…
The First RELHIC? Cloud-9 is a Starless Gas Cloud
Gagandeep S. Anand, Alejandro Benítez-Llambay, Rachael Beaton +3
Five-hundred-meter Aperture Spherical Telescope (FAST) observations have recently identified a compact HI cloud (hereafter Cloud-9) in the vicinity of the spiral galaxy M94. This i…
Invisible Accretion: Ionized Envelopes of TNG50 HVCs can Sustain Star Formation
Scott Lucchini, Jiwon Jesse Han, Lars Hernquist +2
Galactic high-velocity clouds (HVCs) are known to be complex, multiphase systems consisting of neutral and/or ionized gas moving at high velocities relative to the rotation of the…
A Pre-Infall Magellanic Analog-Corona and Stream formation in the \textsc{HESTIA} cosmological simulations
Robin Chisholm, Elena D'Onghia, Noam Libeskind +3
We identify and investigate a pre-infall analog of the Large and Small Magellanic Clouds (LMC, SMC) in the HESTIA suite of constrained cosmological simulations. The system, dynamic…
MUSE-ALMA Haloes X: The stellar masses of gas-rich absorbing galaxies
Ramona Augustin, Céline Péroux, Arjun Karki +13
The physical processes by which gas is accreted onto galaxies, transformed into stars and then expelled from galaxies are of paramount importance to galaxy evolution studies. Obser…
