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…
Dust removal timescale in galaxies across cosmic time
Aleksandra Leśniewska, 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…
The Fate of the Interstellar Medium in Early-type Galaxies. V. AGN Feedback from Optical Spectral Classification
Oleh Ryzhov, Michał J. Michałowski, J. Nadolny +6
Quenching of star-formation plays a fundamental role in galaxy evolution. This process occurs due to the removal of the cold interstellar medium (ISM) or stabilization against coll…
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 ei…
Rapid Dust Formation in the Early Universe
Danial Langeroodi, Jens Hjorth, Andrea Ferrara +1
Interstellar dust links the formation of the first stars to the rocky planet we inhabit by playing a pivotal role in the cooling and fragmentation of molecular clouds, and catalyzi…
The fate of the interstellar medium in early-type galaxies. IV. The impact of stellar feedback, mergers, and black holes on the cold ISM in simulated galaxies
Jakub Nadolny, Michał J. Michałowski, Massimiliano Parente +6
Removing cold interstellar medium (ISM) from a galaxy is central to quenching star formation. However, the exact mechanism of this process remains unclear. The objective of this wo…
The fate of the interstellar medium in early-type galaxies. III. The mechanism of ISM removal and quenching of star formation
Michał J. Michałowski, C. Gall, J. Hjorth +15
Understanding how galaxies quench their star formation is crucial for studies of galaxy evolution. Quenching is related to the cold gas decrease. In the first paper we showed that…
The fate of the interstellar medium in early-type galaxies. I. First direct measurement of the timescale of dust removal
Michał J. Michałowski, J. Hjorth, C. Gall +12
An important aspect of quenching star formation is the removal of the cold interstellar medium (ISM; non-ionised gas and dust) from a galaxy. In addition, dust grains can be destro…
Maximally dusty star-forming galaxies: Supernova dust production and recycling in Local Group and high-redshift galaxies
Christa Gall, Jens Hjorth
Motivated by recent observations suggesting that core-collapse supernovae may on average produce ~0.3 M_sun of dust, we explore a simple dust production scenario which applies to s…
Dust grain growth in the interstellar medium of 5<z<6.5 quasars
Michał J. Michałowski, Eric J. Murphy, Jens Hjorth +3
We investigate whether stellar dust sources i.e. asymptotic giant branch (AGB) stars and supernovae (SNe) can account for dust detected in 5<z<6.5 quasars (QSOs). We calculate the…
