A systematic survey for hypervelocity runaways from thermonuclear supernovae
Kareem El-Badry, Klaus Werner, Ken J. Shen +16
The explosion of a white dwarf (WD) in a close binary can launch a surviving runaway star at velocities of . Such runaways provide a direct probe of…
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…
Threading the Magellanic Needle: Hypervelocity Stars Trace the Past Location of the LMC
Scott Lucchini, Jiwon Jesse Han
Recent discoveries have shown that a population of hypervelocity stars (HVSs) originate from the Large Magellanic Cloud (LMC). We use three such HVSs as dynamical tracers to constr…
Backlighting young stellar objects in the Central Molecular Zone: an ensemble-averaged abundance structure of methanol ices
Yewon Kang, Deokkeun An, Jiwon Han +5
The Central Molecular Zone (CMZ) contains a substantial reservoir of dense molecular gas, where numerous young stellar objects (YSOs) and dense cloud cores have been identified. Ho…
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…
Exploring the interaction between the MW and LMC with a large sample of blue horizontal branch stars from the DESI survey
Amanda Byström, Sergey E. Koposov, Sophia Lilleengen +42
The Large Magellanic Cloud (LMC) is a Milky Way (MW) satellite that is massive enough to gravitationally attract the MW disc and inner halo, causing significant motion of the inner…
