Supersonic Motion in the Driving Region of M82
Skylar Grayson, Evan Scannapieco, Philipp Grete +5
The prototypical starburst galaxy M82 is host to an expansive, multiphase outflow whose driving mechanism is not fully understood. Longstanding models suggest that energy and mass…
Constraints on Binarity for the Extreme Oe Variable Star AzV 493
M. S. Oey, Irene Vargas-Salazar, Edmund Hodges-Kluck +6
The extreme Oe star AzV 493 is known to show unusual photometric and spectroscopic variability that suggest the presence of an unseen companion in a highly eccentric and long-perio…
Revisiting the Claim for a Direct-Collapse Black Hole in UHZ1 at
Fan Zou, Elena Gallo, Zihao Zuo +7
We reassess the direct collapse black hole (DCBH) interpretation of UHZ1 (UNCOVER-26185), a gravitationally lensed galaxy at . That interpretation rests on…
A Fast, Hot Wind from a Nuclear Starburst
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137
Galaxies with intense star formation often host multiphase, galaxy-scale winds powered by supernovae and fast stellar winds. These are strong enough to disrupt the star-forming int…
