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…
Expanding the ultracompacts: gravitational wave-driven mass transfer in the shortest-period binaries with accretion disks
Joheen Chakraborty, Kevin B. Burdge, Saul A. Rappaport +35
We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This significantly augments…
A cosmic formation site of silicon and sulphur revealed by a new type of supernova explosion
Steve Schulze, Avishay Gal-Yam, Luc Dessart +47
The cores of stars are the cosmic furnaces where light elements are fused into heavier nuclei. The fusion of hydrogen to helium initially powers all stars. The ashes of the fusion…
ZTF SN Ia DR2: Overview
Mickael Rigault, Mathew Smith, Ariel Goobar +53
We present the first homogeneous release of several thousand Type Ia supernovae (SNe Ia), all having spectroscopic classification, and spectroscopic redshifts for half the sample.…
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…
Sample of hydrogen-rich superluminous supernovae from the Zwicky Transient Facility
P. J. Pessi, R. Lunnan, J. Sollerman +26
Hydrogen-rich superluminous supernovae (SLSNe II) are rare. The exact mechanism producing their extreme light curve peaks is not understood. Analysis of single events and small sam…
Searching for New Cataclysmic Variables in the Chandra Source Catalog
Ilkham Galiullin, Antonio C. Rodriguez, Kareem El-Badry +14
Cataclysmic variables (CVs) are compact binary systems in which a white dwarf accretes matter from a Roche-lobe-filling companion star. In this study, we searched for new CVs in th…
Searching for gravitational wave optical counterparts with the Zwicky Transient Facility: summary of O4a
Tomás Ahumada, Shreya Anand, Michael W. Coughlin +49
During the first half of the fourth observing run (O4a) of the International Gravitational Wave Network (IGWN), the Zwicky Transient Facility (ZTF) conducted a systematic search fo…
Sub-relativistic Outflow and Hours-Timescale Large-amplitude X-ray Dips during Super-Eddington Accretion onto a Low-mass Massive Black Hole in the Tidal Disruption Event AT2022lri
Yuhan Yao, Muryel Guolo, Francesco Tombesi +32
We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby ( Mpc) quiescent galaxy with a low-mass massive black hole ($10^4\,M_\odot < M_{\rm BH} < 10…
SN 2023zaw: an ultra-stripped, nickel-poor supernova from a low-mass progenitor
Kaustav K. Das, Christoffer Fremling, Mansi M. Kasliwal +34
We present SN 2023zaw a sub-luminous ( mag) and rapidly-evolving supernova ( days), with the lowest nickel mass (…
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…
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…
