Supernova rates and luminosity functions from ASAS-SN II: 2014-2017 core-collapse supernovae and their subtypes
T. Pessi, D. D. Desai, J. L. Prieto +7
The volumetric rates and luminosity functions (LFs) of core-collapse supernovae (ccSN) and their subtypes are important for understanding the cosmic history of star formation and t…
A Systematic Search for Big Dippers in ASAS-SN
B. JoHantgen, D. M. Rowan, R. Forés-Toribio +6
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplan…
MUSE IFU observations of galaxies hosting Tidal Disruption Events
M. Pursiainen, G. Leloudas, J. Lyman +14
We present an analysis of twenty tidal disruption event (TDE) host galaxies observed with the MUSE integral-field spectrograph on ESO VLT. We investigate the presence of extended e…
The Unhurried Universe: A Continued Search for Long Term Variability in ASAS-SN
Sydney Petz, C. S. Kochanek, K. Z. Stanek +4
We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larg…
Citizen ASAS-SN Data Release II: Variable Star Classification Using Citizen Science
O. Kotrach, C. S. Kochanek, C. T. Christy +5
We present the second results from Citizen ASAS-SN, a citizen science project for the All-Sky Automated Survey for Supernovae (ASAS-SN) hosted on the Zooniverse platform. Citizen A…
Discovery and Follow-up of ASASSN-23bd (AT 2023clx): The Lowest Redshift and Least Luminous Tidal Disruption Event To Date
W. B. Hoogendam, J. T. Hinkle, B. J. Shappee +23
We report the All-Sky Automated Survey for SuperNovae discovery of the tidal disruption event (TDE) ASASSN-23bd (AT 2023clx) in NGC 3799, a LINER galaxy with no evidence of strong…
Supernova Rates and Luminosity Functions from ASAS-SN I: 2014--2017 Type Ia SNe and Their Subtypes
D. D. Desai, C. S. Kochanek, B. J. Shappee +9
We present the volumetric rates and luminosity functions (LFs) of Type Ia supernovae (SNe Ia) from the -band All-Sky Automated Survey for Supernovae (ASAS-SN) catalogues spannin…
Progenitor, environment, and modelling of the interacting transient, AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +67
We present the bolometric lightcurve, identification and analysis of the progenitor candidate, and preliminary modelling of AT2016jbu (Gaia16cfr). We find a progenitor consistent w…
To TDE or not to TDE: The luminous transient ASASSN-18jd with TDE-like and AGN-like qualities
J. M. M. Neustadt, T. W. -S. Holoien, C. S. Kochanek +26
We present the discovery of ASASSN-18jd (AT 2018bcb), a luminous optical/UV/X-ray transient located in the nucleus of the galaxy 2MASX J22434289--1659083 at . Over the ye…
The ASAS-SN Catalog of Variable Stars III: Variables in the Southern TESS Continuous Viewing Zone
T. Jayasinghe, K. Z. Stanek, C. S. Kochanek +13
The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline ( yrs) light curves for sources brighter than V mag across the whole sky. The Tran…
Early Spectra of the Gravitational Wave Source GW170817: Evolution of a Neutron Star Merger
B. J. Shappee, J. D. Simon, M. R. Drout +33
On 2017 August 17, Swope Supernova Survey 2017a (SSS17a) was discovered as the optical counterpart of the binary neutron star gravitational wave event GW170817. We report time-seri…
Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy
Subhash Bose, Subo Dong, A. Pastorello +55
Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…
