X-Sifter: detecting transients in X-ray data using the optimal Poisson matched filter
Maayane T. Soumagnac, Eran O. Ofek, Shachar S. Israeli +2
We present X-sifter, a software package designed for near-optimal detection of sources in X-ray images and other forms of photon images in the Poisson-noise regime. The code is bas…
CuRIOS-ED: The Technology Demonstrator for the CubeSats for Rapid Infrared and Optical Surveys Mission
Hannah Gulick, Jessica R. Lu, Aryan Sood +9
The rise of time-domain astronomy including electromagnetic counterparts to gravitational waves, gravitational microlensing, explosive phenomena, and even astrometry with Gaia, are…
An efficient observational strategy for the detection of the Oort cloud
Eran O. Ofek, Sarah A. Spitzer, Guy Nir
The Oort cloud is presumably a pristine relic of the Solar System formation. Detection of the Oort cloud may provide information regarding the stellar environment in which the Sun…
Optical and Radio Analysis of Systematically Classified Broad-lined Type Ic Supernovae from the Zwicky Transient Facility
Gokul P. Srinivasaragavan, Sheng Yang, Shreya Anand +35
We study a magnitude-limited sample of 36 Broad-lined Type Ic Supernovae (SNe Ic-BL) from the Zwicky Transient Facility Bright Transient Survey (detected between March 2018 and Aug…
ZTF SN Ia DR2: The spectral diversity of Type Ia supernovae in a volume-limited sample
U. Burgaz, K. Maguire, G. Dimitriadis +30
More than 3000 spectroscopically confirmed Type Ia supernovae (SNe Ia) are presented in the Zwicky Transient Facility SN Ia Data Release 2 (ZTF DR2). In this paper, we detail the s…
TRANSLIENT: Detecting Transients Resulting from Point Source Motion or Astrometric Errors
O. Springer, E. O. Ofek, B. Zackay +10
Detection of moving sources over complicated background is important for several reasons. First is measuring the astrophysical motion of the source. Second is that such motion resu…
Asteroid collisions: expected visibility and rate
E. O. Ofek, D. Polishook, D. Kushnir +9
Asteroid collisions are one of the main processes responsible for the evolution of bodies in the main belt. Using observations of the Dimorphos impact by the DART spacecraft, we es…
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…
