Early Optical Follow-up of Gamma-Ray Bursts: The Critical Role of Robotic Telescopes
Rahul Gupta, Judith Racusin, Gor Oganesyan +26
Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, and offer unique laboratories for studying relativistic jets, compact-object formation, pa…
A 1.3 cm spectral line study of the W33 region
Kadirya Tursun, Christian Henkel, Jarken Esimbek +14
At a distance of 2.4kpc, W33 is one of the most prolific sources of molecular line emission, and it is an excellent research target for a centimeter spectral line search. We carrie…
Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification
T. Komesh, A. Pozanenko, N. Pankov +37
We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt gamma-ray observations with exceptionally early simultaneous optical photometr…
A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However,…
Cloud-cloud collision and star formation in G013.313+0.193
Dilda Berdikhan, Jarken Esimbek, Christian Henkel +18
We study the G013.313+0.193 G013.313 region, a complex environment characterized by molecular cloud interactions indicative of cloud-cloud collision (CCC). Observations of the NH3(…
Evidence for Core-Core Collision in Barnard 68
Dalei Li, Christian Henkel, Alexander Kraus +10
The prestellar core Barnard 68 (B68) is a prototypical source to study the initial conditions and chemical processes of star formation. A previous numerical simulation suggested th…
