Evolution of the Mass-Metallicity Relation from Redshift to the Local Universe
Danial Langeroodi, Jens Hjorth, Wenlei Chen +17
A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of this correlation can s…
SN 2022ann: A type Icn supernova from a dwarf galaxy that reveals helium in its circumstellar environment
K. W. Davis, K. Taggart, S. Tinyanont +64
We present optical and near-infrared (NIR) observations of the Type Icn supernova (SN Icn) 2022ann, the fifth member of its newly identified class of SNe. Its early optical spectra…
The Young Supernova Experiment Data Release 1 (YSE DR1): Light Curves and Photometric Classification of 1975 Supernovae
P. D. Aleo, K. Malanchev, S. Sharief +80
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry of 1…
A Magnified Compact Galaxy at Redshift 9.51 with Strong Nebular Emission Lines
Hayley Williams, Patrick L. Kelly, Wenlei Chen +21
Ultraviolet light from early galaxies is thought to have ionized gas in the intergalactic medium. However, there are few observational constraints on this epoch because of the fain…
PAH emission from star-forming galaxies in JWST mid-infrared imaging of the lensing cluster SMACS J0723.37327
Danial Langeroodi, Jens Hjorth
The mid-infrared spectra of star-forming galaxies (SFGs) are characterized by characteristic broad PAH emission features at 3-20 m. As these features are redshifted, they are pr…
Relative intrinsic scatter in hierarchical Type Ia supernova siblings analyses: Application to SNe 2021hpr, 1997bq & 2008fv in NGC 3147
Sam M. Ward, Stephen Thorp, Kaisey S. Mandel +22
We present Young Supernova Experiment photometry of SN 2021hpr, the third Type Ia supernova sibling to explode in the Cepheid calibrator galaxy, NGC 3147. Siblings are usef…
N-bearing complex organics toward high-mass protostars: Constant ratios pointing to formation in similar pre-stellar conditions across a large mass range
P. Nazari, J. D. Meijerhof, M. L. van Gelder +10
No statistical study of COMs toward a large sample of high-mass protostars with ALMA has been carried out so far. We aim to study six N-bearing species: CHCN, HNCO, NHCHO,…
Photometric redshift estimation of strongly lensed galaxies
Danial Langeroodi, Alessandro Sonnenfeld, Henk Hoekstra +1
Around strongly lensed galaxies are expected to be discovered with Euclid and the LSST. Utilising these large samples to study the inner structure of lens galaxies requires…
The Circumstellar Environments of Double-Peaked, Calcium-strong Supernovae 2021gno and 2021inl
Wynn Jacobson-Galán, Padma Venkatraman, Raffaella Margutti +42
We present panchromatic observations and modeling of calcium-strong supernovae (SNe) 2021gno in the star-forming host galaxy NGC 4165 (D = 30.5 Mpc) and 2021inl in the outskirts of…
