Extending the cosmic distance ladder two orders of magnitude with strongly lensed Cepheids, carbon AGB, and RGB stars
J. M. Diego, S. P. Willner, J. M. Palencia +1
Gravitational lensing by galaxy clusters can create extreme magnification near the cluster caustics, thereby enabling detection of individual luminous stars in high-redshift backgr…
Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr
E. Vanzella, F. Loiacono, M. Messa +38
We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…
Spectroscopic analysis of the strongly lensed SN~Encore: Constraints on cosmic evolution of Type Ia supernovae
S. Dhawan, J. D. R. Pierel, M. Gu +16
Strong gravitational lensing magnifies the light from a background source, allowing us to study these sources in detail. Here, we study the spectra of a lensed Type Ia s…
Anatomy of a z=6 Lyman-α emitter down to parsec scales: extreme UV slopes, metal-poor regions and possibly leaking star clusters
Matteo Messa, E. Vanzella, F. Loiacono +31
We present a detailed JWST/NIRSpec and NIRCam analysis of a gravitationally-lensed galaxy () at redshift 6.14 magnified by the Hubble Frontier Field galaxy cluster MAC…
JWST's PEARLS: resolved study of the stellar and dust components in starburst galaxies at cosmic noon
M. Polletta, B. L. Frye, N. Garuda +35
Dusty star-forming galaxies (DSFGs) contribute significantly to the stellar buildup at cosmic noon. Major mergers and gas accretion are often invoked to explain DSFGs' prodigious s…
Lensed Type Ia Supernova "Encore" at z=2: The First Instance of Two Multiply-Imaged Supernovae in the Same Host Galaxy
J. D. R. Pierel, A. B. Newman, S. Dhawan +60
A bright (=24 mag), supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply-imaged as a result o…
