Cosmology with Supernova Encore in the lensing cluster MACS J01382155 -- Spectroscopy with MUSE
G. Granata, G. B. Caminha, S. Ertl +9
We present a spectroscopic analysis of MACS J01382155, at , the first galaxy cluster hosting two strongly-lensed supernovae (SNe), Requiem and Encore, providing us with…
Seven wonders of Cosmic Dawn: JWST confirms a high abundance of galaxies and AGNs at z 9-11 in the GLASS field
L. Napolitano, M. Castellano, L. Pentericci +24
We present JWST/NIRSpec PRISM follow-up of candidate galaxies at z=9-11 selected from deep JWST/NIRCam photometry in GLASS-JWST Early Release Science data. We spectroscopically con…
The next step in galaxy cluster strong lensing: modeling the surface brightness of multiply-imaged sources
Ana Acebron, Claudio Grillo, Sherry H. Suyu +12
Overcoming both modeling and computational challenges, we present, for the first time, the extended surface-brightness distribution model of a strongly-lensed source in a complex g…
Accelerated Emergence of Evolved Galaxies in Early Overdensities at
Takahiro Morishita, Zhaoran Liu, Massimo Stiavelli +8
We report the identification of two galaxy overdensities at in the sightline of the galaxy cluster Abell 2744. These overdensities consist of 25 and 17 member galaxies,…
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…
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…
Euclid: Early Release Observations -- A preview of the Euclid era through a galaxy cluster magnifying lens
H. Atek, R. Gavazzi, J. R. Weaver +200
We present the first analysis of the Euclid Early Release Observations (ERO) program that targets fields around two lensing clusters, Abell 2390 and Abell 2764. We use VIS and NISP…
HOLISMOKES XIII: Strong-lens candidates at all mass scales and their environments from the Hyper-Suprime Cam and deep learning
Stefan Schuldt, Raoul Cañameras, Irham T. Andika +6
We performed a systematic search for strong gravitational lenses using Hyper Suprime-Cam (HSC) data, focusing on galaxy-scale lenses combined with an environment analysis resulting…
Strong-lensing and kinematic analysis of CASSOWARY 31: can strong lensing constrain the masses of multi-plane lenses?
H. Wang, R. Canameras, S. H. Suyu +4
We present a mass measurement for the secondary lens along the line of sight (LoS) in the multi-plane strong lens modeling of the group-scale lens CASSOWARY 31 (CSWA 31). The secon…
