Palomar discovery and initial characterization of naked-eye long period comet C/2022 E3 (ZTF)

B. T. Bolin, F. J. Masci, D. A. Duev +11

Long-period comets are planetesimal remnants constraining the environment and volatiles of the protoplanetary disc. We report the discovery of hyperbolic long-period comet C/2022 E…

An Optically-Discovered Outburst from XTE J1859+226

Eric C. Bellm, Yuankun Wang, Jan van Roestel +13

Using the Zwicky Transient Facility, in 2021 February we identified the first known outburst of the Black Hole X-ray Transient XTE J1859+226 since its discovery in 1999. The outbur…

Panic at the ISCO: time-varying double-peaked broad lines from evolving accretion disks are common amongst optically variable AGN

Charlotte Ward, Suvi Gezari, Peter Nugent +12

About 3-10\% of Type I active galactic nuclei (AGN) have double-peaked broad Balmer lines in their optical spectra originating from the motion of gas in their accretion disk. Doubl…

SN 2022joj: A Peculiar Type Ia Supernova Possibly Driven by an Asymmetric Helium-shell Double Detonation

Chang Liu, Adam A. Miller, Samuel J. Boos +28

We present observations of SN 2022joj, a peculiar Type Ia supernova (SN Ia) discovered by the Zwicky Transient Facility (ZTF). SN 2022joj exhibits an unusually red $g_\mathrm{ZTF}-…

Zwicky Transient Facility and Globular Clusters: the gr-Band Period-Luminosity Relations for Mira Variables at Maximum Light and Their Applications to Local Galaxies

Chow-Choong Ngeow, Jia-Yu Ou, Anupam Bhardwaj +3

Based on 14 Miras located in 7 globular clusters, we derived the first gr-band period-luminosity (PL) at maximum light for the large-amplitude Mira variables using the multi-year l…

SRGeJ045359.9+622444: A 55-min Period Eclipsing AM CVn Discovered from a Joint SRG/eROSITA + ZTF Search

Antonio C. Rodriguez, Ilkham Galiullin, Marat Gilfanov +24

AM CVn systems are ultra-compact binaries where a white dwarf accretes from a helium-rich degenerate or semi-degenerate donor. Some AM CVn systems will be among the loudest sources…

Probing pre-supernova mass loss in double-peaked Type Ibc supernovae from the Zwicky Transient Facility

Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +34

Eruptive mass loss of massive stars prior to supernova (SN) explosion is key to understanding their evolution and end fate. An observational signature of pre-SN mass loss is the de…
