Since the expansion of the universe was first established by Edwin Hubble and Georges
Lemaître about a century ago, the Hubble constant H_0 H 0 which measures its rate has …

We develop a hybrid model of galactic chemical evolution that combines a multiring
computation of chemical enrichment with a prescription for stellar migration and the vertical …

Abstract The Asteroid Terrestrial impact Last Alert System (ATLAS) system consists of two
0.5 m Schmidt telescopes with cameras covering 29 square degrees at plate scale of 1.86 …

Abstract The Zwicky Transient Facility (ZTF) is performing a three-day cadence survey of the
visible northern sky (∼ 3π) with newly found transient candidates announced via public …

We present the first version of the Automatic Learning for the Rapid Classification of Events
(ALeRCE) broker light curve classifier. ALeRCE is currently processing the Zwicky Transient …

Abstract The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long-baseline
(∼ 4 yr) light curves for sources brighter than V≲ 17 mag across the whole sky. The …

We present the results from a search for gravitational-wave transients associated with core-
collapse supernovae observed within a source distance of approximately 20 Mpc during the …

We present the discovery and early evolution of ASASSN-19bt, a tidal disruption event
(TDE) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) at a distance …

ABSTRACT The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long
