Galaxy Zoo Evo: 1 million human-annotated images of galaxies
Mike Walmsley, Steven Bamford, Hugh Dickinson +17
We introduce Galaxy Zoo Evo, a labeled dataset for building and evaluating foundation models on images of galaxies. GZ Evo includes 104M crowdsourced labels for 823k images from fo…
HOLISMOKES XIX: SN 2025wny at , the first strongly lensed superluminous supernova
Stefan Taubenberger, Ana Acebron, Raoul Cañameras +45
We present imaging and spectroscopic observations of supernova SN 2025wny, associated with the lens candidate PS1 J0716+3821. Photometric monitoring from the Lulin and Maidanak obs…
A Nitrogen-rich AGN Powering a Large Ionizing Bubble at z=8.63
Takahiro Morishita, Massimo Stiavelli, Charlotte A. Mason +5
We report the detection of Ly in CANUCS-LRD-z8.6, a recently discovered AGN at z = 8.63 by Tripodi et al. (2024), in new NIRSpec/MSA G140H/F070LP observations. We detect broad L…
HOLISMOKES XVII: Detecting strongly lensed SNe Ia from time series of multi-band LSST-like imaging data
Satadru Bag, Raoul Canameras, Sherry H. Suyu +4
Strong gravitationally lensed supernovae (LSNe), though rare, are exceptionally valuable probes for cosmology and astrophysics. Upcoming time-domain surveys like the Vera Rubin Obs…
A stellar dynamical mass measurement of an inactive black hole at redshift 2
Andrew B. Newman, Meng Gu, Sirio Belli +34
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…
Cosmology with supernova Encore in the strong lensing cluster MACS J01382155: photometry, cluster members, and lens mass model
S. Ertl, S. H. Suyu, S. Schuldt +23
The strongly lensed Supernova (SN) Encore at a redshift of , discovered behind the galaxy cluster MACS J01382155 at , provides a rare opportunity for time-de…
Enhanced strong-lensing model of MACS~J0138.02155 based on new JWST and VLT/MUSE observations
Ana Acebron, Pietro Bergamini, Piero Rosati +10
We present a new parametric strong lensing analysis of the galaxy cluster MACS J0138.0-2155 at z = 0.336, the first known to show two multiply-imaged supernova (SN) siblings, SN Re…
Accelerating lensed quasar discovery and modeling with physics-informed variational autoencoders
Irham T. Andika, Stefan Schuldt, Sherry H. Suyu +5
Strongly lensed quasars provide valuable insights into the rate of cosmic expansion, the distribution of dark matter in foreground deflectors, and the characteristics of quasar hos…
