Resolving the explosion of supernova 2023ixf in Messier 101 within its complex circumstellar environment
E. A. Zimmerman, I. Irani, P. Chen +54
Observing a supernova explosion shortly after it occurs can reveal important information about the physics of stellar explosions and the nature of the progenitor stars of supernova…
Broad-emission-line dominated hydrogen-rich luminous supernovae
P. J. Pessi, J. P. Anderson, G. Folatelli +27
Hydrogen-rich Type II supernovae (SNe II) are the most frequently observed class of core-collapse SNe (CCSNe). However, most studies that analyse large samples of SNe II lack event…
ULTRASAT: A wide-field time-domain UV space telescope
Y. Shvartzvald, E. Waxman, A. Gal-Yam +41
The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is scheduled to be launched to geostationary orbit in 2026. It will carry a telescope with an unprecedentedly large field o…
The Large Array Survey Telescope -- System Overview and Performances
E. O. Ofek, S. Ben-Ami, D. Polishook +38
The Large Array Survey Telescope (LAST) is a wide-field visible-light telescope array designed to explore the variable and transient sky with a high cadence. LAST will be composed…
The Large Array Survey Telescope -- Science Goals
S. Ben-Ami, E. O. Ofek, D. Polishook +20
The Large Array Survey Telescope (LAST) is designed to survey the variable and transient sky at high temporal cadence. The array is comprised of 48 F/2.2 telescopes of 27.9cm apert…
The broad-lined Type-Ic supernova SN 2022xxf with extraordinary two-humped light curves
H. Kuncarayakti, J. Sollerman, L. Izzo +60
We report on our study of supernova (SN) 2022xxf based on observations obtained during the first four months of its evolution. The light curves (LCs) display two humps of similar m…
