Deep view of the intracluster light in the Coma cluster of galaxies
Yolanda Jiménez-Teja, Javier Román, Kim HyeongHan +6
Detection and study of the intracluster light in rich clusters of galaxies has been a problem of long standing challenge and interest. Using the lowest surface brightness images of…
Cyclotron emitting magnetic white dwarfs in post common envelope binaries discovered with the Zwicky Transient Facility
J. van Roestel, A. C. Rodriguez, P. Szkody +20
We present the discovery of 14 new (and recovery of 4 known) low accretion rate magnetic white dwarfs in post-common envelope binaries that emit strong cyclotron emission using the…
Cataclysmic Variables and AM CVn Binaries in SRG/eROSITA + Gaia: Volume Limited Samples, X-ray Luminosity Functions, and Space Densities
Antonio C. Rodriguez, Kareem El-Badry, Valery Suleimanov +22
We present volume-limited samples of cataclysmic variables (CVs) and AM CVn binaries jointly selected from SRG/eROSITA eRASS1 and \textit{Gaia} DR3 using an X-ray + optical color-c…
Comet C/2012 S1 (ISON) crossing the Jupiter orbit
Margarita Safonova, Noah Brosch, Shai Kaspi +4
We report results of intensive time-resolved imaging photometry and synoptic deep imaging of the comet C/2012 S1 (ISON) performed in February 2013. The data were obtained at the Wi…
Dramatic rebrightening of the type-changing stripped-envelope supernova SN 2023aew
Yashvi Sharma, Jesper Sollerman, Shrinivas R. Kulkarni +32
Multi-peaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-s…
A Survey for Radio Emission from White Dwarfs in the VLA Sky Survey
Ingrid Pelisoli, Laura Chomiuk, Jay Strader +22
Radio emission has been detected from tens of white dwarfs, in particular in accreting systems. Additionally, radio emission has been predicted as a possible outcome of a planetary…
RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99
Evan Butler, Andrea Kunder, Zdenek Prudil +16
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…
The 2022-2023 accretion outburst of the young star V1741 Sgr
Michael A. Kuhn, Lynne A. Hillenbrand, Michael S. Connelley +12
V1741 Sgr (= SPICY 71482/Gaia22dtk) is a Classical T Tauri star on the outskirts of the Lagoon Nebula. After at least a decade of stability, in mid-2022, the optical source brighte…
Spectroscopic observations of progenitor activity 100 days before a Type Ibn supernova
S. J. Brennan, J. Sollerman, I. Irani +30
Obtaining spectroscopic observations of the progenitors of core-collapse supernovae is often unfeasible due to an inherent lack of knowledge as to which stars will go supernova and…
