SN 2022riv in RX J2129: Discovery, Spectroscopic Classification, and Microlensing of a Strongly Lensed Type Ia Supernova from JWST and HST Observations
Birendra Dhanasingham, Patrick L. Kelly, Wenlei Chen +27
The multiply imaged SN 2022riv was discovered through a search of galaxy cluster fields as part of a Hubble Space Telescope (HST) SNAP program to find highly magnified stars. The s…
The Hubble Constant from Blue Type Ia Supernovae
Christa Gall, Luca Izzo, Radoslaw Wojtak +1
There is a persistent tension of about between the value of the Hubble constant, as derived from the local distance ladder vs. the cosmic microwave background, signaling…
Dust removal timescale in galaxies across cosmic time
Aleksandra LeÅniewska, Jens Hjorth, Christa Gall
Understanding the evolution of dust in galaxies is crucial because it affects the dynamics and cooling of gas, star formation, and chemical evolution. Recent work on dust removal i…
AAS2RTO: Automated Alert Streams to Real-Time Observations: Preparing for rapid follow-up of transient objects in the era of LSST
Aidan Sedgewick, Christa Gall, Luca Izzo +4
The upcoming Vera C. Rubin Legacy Survey of Space and Time (LSST) will discover tens of thousands of astrophysical transients per night, far outpacing available spectroscopic follo…
