Seeing Double: The Theory Defying Twin Flares of TDE 2022dbl
Xinze Guo, Ryan Chornock, Raffaella Margutti +13
Partial tidal disruption events, in which a star survives a close passage by a supermassive black hole and may be disrupted again on a subsequent encounter, provide a unique probe…
An Off-Nuclear Tidal Disruption Event Discovered At Late Times: The Case Of TDE 2023mfm
Itai Sfaradi, Ryan Chornock, Yuhan Yao +24
We present the discovery and analysis of the optically selected tidal disruption event (TDE) 2023mfm, which originates from a wandering massive black hole (MBH) in a massive ($\sim…
First Pre-peak Ultraviolet Spectrum of a Tidal Disruption Event: A Fast Outflow Revealed Prior to Maximum Light in TDE2025aarm
Erica Hammerstein, Ryan Chornock, Jean Somalwar +32
The tidal disruption and eventual accretion of a star by a massive black hole can lead to the launching of outflows and winds that encode important information about the tidal disr…
Rubin ToO 2024: Envisioning the Vera C. Rubin Observatory LSST Target of Opportunity program
Igor Andreoni, Raffaella Margutti, John Banovetz +86
The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory is planned to begin in the Fall of 2025. The LSST survey cadence has been designed via a community-driven pr…
: An Accurate Photometric Classifier for Tidal Disruption Events
Robert Stein, Ashish Mahabal, Simeon Reusch +12
Optical surveys have become increasingly adept at identifying candidate Tidal Disruption Events (TDEs) in large numbers, but classifying these generally requires extensive spectros…
The first systematically identified repeating partial tidal disruption event
Jean J. Somalwar, Vikram Ravi, Yuhan Yao +13
Tidal disruption events (TDEs) occur when a star enters the tidal radius of a supermassive black hole (SMBH). If the star only grazes the tidal radius, a fraction of the stellar ma…
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}-…
Enabling Kilonova Science with Nancy Grace Roman Space Telescope
Igor Andreoni, Michael W. Coughlin, Alexander W. Criswell +16
Binary neutron star mergers and neutron star-black hole mergers are multi-messenger sources that can be detected in gravitational waves and in electromagnetic radiation. The low el…
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…
Long-rising Type II Supernovae in the Zwicky Transient Facility Census of the Local Universe
Tawny Sit, Mansi M. Kasliwal, Anastasios Tzanidakis +25
SN 1987A was an unusual hydrogen-rich core-collapse supernova originating from a blue supergiant star. Similar blue supergiant explosions remain a small family of events, and are b…
Tidal Disruption Event Demographics with the Zwicky Transient Facility: Volumetric Rates, Luminosity Function, and Implications for the Local Black Hole Mass Function
Yuhan Yao, Vikram Ravi, Suvi Gezari +26
We conduct a systematic tidal disruption event (TDE) demographics analysis using the largest sample of optically selected TDEs. A flux-limited, spectroscopically complete sample of…
Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky
Ariel Goobar, Joel Johansson, Steve Schulze +35
Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a s…
