A DECADE of Giants: A catalog of 42,000 optically identified galaxy clusters from 13,000 of the sky
D. Anbajagane, C. To, M. Gaido +44
Galaxy clusters are sensitive to a rich variety of physics spanning a wide dynamic range, from microphysical to cosmological scales. Optical datasets are efficient at identifying c…
Lensing in the Blue IV: The First Weak Gravitational Lensing Maps from the Stratosphere
Sayan Saha, Maya Amit, Jacqueline E. McCleary +42
The Super-Pressure Balloon-borne Imaging Telescope (SuperBIT) completed its science flight in April 2023, obtaining imaging data for 30 galaxy clusters. In this work, we present th…
The extreme Disturbed Galaxy Cluster Sample (eDGeS): Spectroscopy and Dynamical Analysis of the eROSITA-Selected Merging Galaxy Cluster Candidate 1eRASS J025859.4-193727
Anish S. Aradhey, Eleazar R. Carrasco, Alfredo Zenteno +7
Addressing open questions such as the effect of galaxy cluster mergers on the evolution of galaxies and the self-interaction cross-section of dark matter requires the construction…
Mode Switching in Two Blue Large Amplitude Pulsators observed by OGLE, KMTNet and DREAMS
Hao Ma, Shude Mao, Seung-Lee Kim +20
Blue large-amplitude pulsators (BLAPs) are rare, hot, short-period pulsating stars whose rapid oscillations provide a unique probe of stellar interiors and atmospheres. In this pap…
KMT-2026-BLG-0083L: A Two-Jovian-Planet System Orbiting an M Dwarf Discovered by Microlensing
Cheongho Han, Chung-Uk Lee, Zhixing Li +65
We present the analysis of the microlensing event KMT-2026-BLG-0083, which was independently detected by the KMTNet, OGLE, and PRIME surveys and also monitored by the DREAMS survey…
Multi-sensor fusion for fine-guidance and milliarcsecond-level attitude estimation of balloon-borne telescope
Philippe Voyer, Maya Amit, Steven J. Benton +44
Balloon-borne telescopes rely on fine-guidance systems to achieve milliarcsecond image stability despite residual disturbances from the balloon environment. In these systems, the F…
The DECam MAGIC Survey Mapping the Ancient Galaxy in CaHK: Overview and Summary of Early Science
A. Chiti, A. Drlica-Wagner, A. B. Pace +42
We present the DECam Mapping the Ancient Galaxy in CaHK (MAGIC) survey, a 54-night NOIRLab Survey Program to image 5,000deg of the southern hemisphere using a meta…
A Minute-Cadence Deep Bulge Survey: First Data Release of DREAMS
Hongjing Yang, Weicheng Zang, Francisco Valdes +31
The DECam Rogue Earths and Mars Survey (DREAMS), a NOIRLab survey program, has been conducting a three-year survey covering a 5 deg area in the Galactic bulge (roughly spanning…
Lensing in the Blue III: Weak Lensing Shape Catalogs of 30 Merging Galaxy Clusters
Sayan Saha, Jacqueline E. McCleary, Spencer W. Everett +38
We present the weak gravitational lensing dataset from the Super-pressure Balloon-Borne Imaging Telescope (SuperBIT), which imaged 30 galaxy clusters during its 45 night flight in…
KMT-2025-BLG-1616Lb: First Microlensing Bound Planet From DREAMS
Hongjing Yang, Weicheng Zang, Yoon-Hyun Ryu +60
We present observations and analysis of the bound planetary microlensing event KMT-2025-BLG-1616. The planetary signal was captured by the Korea Microlensing Telescope Network (KMT…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
Counterpart identification and classification for eRASS1 and characterisation of the AGN content
M. Salvato, J. Wolf, T. Dwelly +44
[abridged] Accurately accounting for the AGN phase in galaxy evolution requires a large, clean AGN sample. This is now possible with SRG/eROSITA. The public Data Release 1 (DR1, Ja…
DELVE Milky Way Satellite Galaxy Census I: Satellite Population and Survey Selection Function in DES, DELVE, and Pan-STARRS
C. Y. Tan, A. Drlica-Wagner, A. B. Pace +84
The properties of Milky Way satellite galaxies have important implications for galaxy formation, reionization, and the fundamental physics of dark matter. However, the population o…
The effect of dynamical states on galaxy clusters populations. II. Comparison of galaxy properties and fundamental relations
S. Véliz Astudillo, E. R. Carrasco, J. L. Nilo Castellón +2
Galaxy clusters provide a unique environment to study galaxy evolution. The role of cluster dynamical states in shaping the physical and morphological properties of member galaxies…
