A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
A catalog to unite them all: REGALADE, a revised galaxy compilation for the advanced detector era
Hugo Tranin, Nadejda Blagorodnova, Marco A. Gómez-Muñoz +10
Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar ma…
Harnessing the XMM-Newton data: X-ray spectral modelling of 4XMM-DR11 detections and 4XMM-DR11s sources
A. Viitanen, G. Mountrichas, H. Stiele +13
The XMM-Newton X-ray observatory has played a prominent role in astrophysics, conducting precise and thorough observations of the X-ray sky for the past two decades. The most recen…
Hot springs and dust reservoirs: JWST reveals the dusty, molecular aftermath of extragalactic stellar mergers
Viraj Karambelkar, Mansi Kasliwal, Ryan M. Lau +7
We present James Webb Space Telescope (JWST) observations of four Luminous Red Novae (LRNe): dusty, extragalactic transients from stellar mergers following common-envelope evolutio…
The population of hyperluminous X-ray sources as seen by XMM-Newton
Roberta Amato, Erwan Quintin, Hugo Tranin +7
Ultraluminous and hyperluminous X-ray sources (ULXs and HLXs) are among the brightest astrophysical objects in the X-ray sky. While ULXs most likely host stellar-mass compact objec…
Isolated neutron stars as Science Validation for XMM2ATHENA: Ensuring robust data for future X-ray Astronomy
Adriana Mancini Pires, Christian Motch, Axel Schwope +9
The discovery of radio-quiet, X-ray thermally emitting isolated neutron stars (XINSs) in the ROSAT All-Sky Survey revealed a previously overlooked component of the neutron star pop…
