The HERON Coma Project: Exploring the low-surface-brightness frontiers in the Coma cluster
Javier Román, R. Michael Rich, Pablo M. Sánchez-Alarcón +3
The technical complexity of data processing and residual instrumental systematics remain among the main barriers to reaching the faintest low-surface-brightness (LSB) regimes in th…
VENUS: an ultra-faint galaxy hosting the metal-poor type II supernova at Witnessing the initial metal enrichment with extremely frequent core-collapse supernovae?
Yoshihisa Asada, Seiji Fujimoto, Joseph F. V. Allingham +50
We present the first characterization of the host galaxy of a recently discovered type IIP SN at (SN Eos). SN Eos and its host galaxy are gravitationally lensed and multip…
VENUS: Strong-lensing model of MACS J1931.8-2635 -- revealing the farthest multiply imaged supernova
Joseph F. V. Allingham, Adi Zitrin, Vasily Kokorev +42
We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 (), accompanying the detection of the spectroscopically confirmed SN Eos at $z = 5…
A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13
David A. Coulter, Conor Larison, Justin D. R. Pierel +88
Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…
A Closer Look at the Dynamical State of the High-redshift Galaxy Cluster SPT-CL J2215-3537
Vinicius S. Bessa, Renato A. Dupke, Yolanda Jiménez-Teja
We present a comprehensive reanalysis of the dynamical state of the high-redshift galaxy cluster SPT-CL J2215-3537 (z = 1.16), using the full set of available Chandra observations…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: A Low Surface Brightness Science Case
Mireia Montes, Ignacio Trujillo, David Martínez Delgado +27
The Extragalactic Low Surface Brightness (LSB, mag/arcsec) Universe represents a crucial, yet largely unseen, frontier in modern astrophysics. This faint realm…
Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
VENUS: When Red meets Blue -- A multiply imaged Little Red Dot with an apparent blue companion behind the galaxy cluster Abell 383
Miriam Golubchik, Lukas J. Furtak, Joseph F. V. Allingham +50
We report the discovery of a doubly-imaged Little Red Dot (LRD) candidate behind the galaxy cluster Abell 383, which we dub A383-LRD1. Initially classified as a dropout galaxy in H…
VENUS: A Strongly Lensed Clumpy Galaxy at behind the Galaxy Cluster MACS J0257.1-2325
Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75
We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…
J-PLUS: Detecting and studying extragalactic globular clusters -- the case of NGC 1023
Danielle de Brito Silva, Paula Coelho, Arianna Cortesi +19
Extragalactic globular clusters (GCs) are key objects for studying the history of galaxies. The arrival of wide-field surveys such as the Javalambre Photometric Local Universe Surv…
Wavelet theory applied to the study of spectra of trans-Neptunian objects
Ana Carolina Souza-Feliciano, Alvaro Alvarez-Candal, Yolanda Jiménez-Teja
Reflection spectroscopy in the Near Infrared (NIR) is used to investigate the surface composition of Trans-Neptunian objects (TNOs). In general, these spectra are difficult to inte…
