Simultaneous Radio and Optical Polarimetry of GRB 191221B Afterglow
Yuji Urata, Kenji Toma, Stefano Covino +16
Gamma-ray bursts (GRBs) are the most luminous transients in the universe and are utilized as probes of early stars, gravitational wave counterparts, and collisionless shock physics…
Dissecting the interstellar medium of a z=6.3 galaxy: X-shooter spectroscopy and HST imaging of the afterglow and environment of the Swift GRB 210905A
A. Saccardi, S. D. Vergani, A. De Cia +35
The study of the properties of galaxies in the first billion years after the Big Bang is one of the major topic of current astrophysics. Optical/near-infrared spectroscopy of the a…
Laser Guide Star uplink beam: scattering and Raman emission measurements with the 10.4m Gran Telescopio CANARIAS
G. Lombardi, D. Bonaccini Calia, M. Centrone +2
Laser Guide Star Adaptive Optics (LGS-AO) is becoming routine in several astronomical observatories. The use of powerful lasers generates sensible Raman emissions on the uplink las…
The GRANDMA network in preparation for the fourth gravitational-wave observing run
S. Agayeva, V. Aivazyan, S. Alishov +98
GRANDMA is a world-wide collaboration with the primary scientific goal of studying gravitational-wave sources, discovering their electromagnetic counterparts and characterizing the…
EIFIS: a modular extreme integral field spectrograph for the 10.4m GTC
Christina C. Thöne, Antonio de Ugarte Postigo, Marisa García Vargas +4
EIFIS (Extreme Integral FIeld Spectrograph) is a modular integral field spectrograph, based on image slicers, and makes use of new, large format detectors. The concept is thought t…
Multi-wavelength analysis of short GRB 201221D and its comparison with other high \& low redshift short GRBs
Dimple, K. Misra, D. A. Kann +9
We present a detailed analysis of short GRB 201221D lying at redshift . We analyse the high-energy data of the burst and compare it with the sample of short gamma-ray bur…
A Kilonova Following a Long-Duration Gamma-Ray Burst at 350 Mpc
J. C. Rastinejad, B. P. Gompertz, A. J. Levan +32
Here, we report the discovery of a kilonova associated with the nearby (350 Mpc) minute-duration GRB 211211A. In tandem with deep optical limits that rule out the presence of an ac…
A blast from the infant Universe: the very high-z GRB 210905A
A. Rossi, D. D. Frederiks, D. A. Kann +52
We present a detailed follow-up of the very energetic GRB 210905A at a high redshift of z = 6.312 and its luminous X-ray and optical afterglow. We obtained a photometric and spectr…
Cosmological Fast Optical Transients with the Zwicky Transient Facility: A Search for Dirty Fireballs
Anna Y. Q. Ho, Daniel A. Perley, Yuhan Yao +33
Dirty fireballs are a hypothesized class of relativistic massive-star explosions with an initial Lorentz factor below the required to pro…
