The ∞ Galaxy: A Candidate Direct-collapse Supermassive Black Hole between Two Massive, Ringed Nuclei
We report the discovery of an unusual z = 1.14 object, dubbed the ∞ galaxy, in JWST imaging of the COSMOS field. Its rest-frame near-IR light is dominated by two compact nuclei with stellar masses of ∼10 ^11 M _⊙ and a projected separation of 10 kpc ...

AT2021aeuk: A Repeating Partial Tidal Disruption Event Candidate in a Narrow-line Seyfert 1 Galaxy
A black hole (BH) can tear apart a star that ventures within its tidal radius, producing a luminous flare as the stellar debris falls back, known as a tidal disruption event (TDE).

Light and hyper nuclei formation at sNN= 3 GeV Au+Au collisions using Wigner coalescence approach
The production of light nuclei and hyper-nuclei in heavy-ion collisions, particularly at high baryon density, is crucial for understanding the dynamical evolution of the collision system and exploring the internal state of nuclear matter of compacted ...

Embedded Young Stellar Objects near H72.97-69.39: A Forming Super Star Cluster in N79
We present 102 embedded young stellar object (YSO) candidates associated with the H72.97-69.39 super star cluster (SSC) in the Large Magellanic Cloud (LMC).

A Data-driven Search For Mid-infrared Excesses Among Five Million Main-sequence FGK Stars
Stellar infrared excesses can indicate various phenomena of interest, from protoplanetary disks to debris disks, or (more speculatively) techno-signatures along the lines of Dyson spheres.

Detection of Young Massive White Dwarfs in Core-collapsed Globular Cluster NGC 362
Core-collapsed globular clusters are ideal targets to explore the presence of stellar collision products. Here, we have studied 17 far-UV bright white dwarf (WD) members in the globular cluster NGC 362 using data obtained from the Ultra Violet Imaging ...
