Optimization of performance of the KM2A full array using the Crab Nebula
LHAASO collaboration
The full array of the Large High Altitude Air Shower Observatory (LHAASO) has been in operation since July 2021. For its kilometer-square array (KM2A), we have optimized the select…
Optical and Near-infrared Observations of the Distant but Bright 'New Year's Burst' GRB 220101A
Zi-Pei Zhu, Wei-Hua Lei, Daniele B. Malesani +26
High-redshift gamma-ray bursts (GRBs) provide a powerful tool to probe the early universe, but still for relatively few do we have good observations of the afterglow. We here repor…
Flux Variations of Cosmic Ray Air Showers Detected by LHAASO-KM2A During a Thunderstorm on 10 June 2021
LHAASO Collaboration, F. Aharonian, Q. An +268
The Large High Altitude Air Shower Observatory (LHAASO) has three sub-arrays, KM2A, WCDA and WFCTA. The flux variations of cosmic ray air showers were studied by analyzing the KM2A…
The Peculiar Precursor of a Gamma-Ray Burst from a Binary Merger Involving a Magnetar
Shuo Xiao, Yan-Qiu Zhang, Zi-Pei Zhu +42
The milestone discovery of GW 170817-GRB 170817A-AT 2017gfo has shown that gravitational wave (GW) could be produced during the merger of neutron star-neutron star/black hole and t…
GB6 J2113+1121: A multi-wavelength flaring gamma-ray blazar temporally and spatially coincident with the neutrino event IceCube-191001A
Neng-Hui Liao, Zhen-Feng Sheng, Ning Jiang +6
A radio-emitting tidal disruption event (AT2019dsg) is proposed as a likely counterpart of the IceCube neutrino event IC-191001A. In this work we have revisited the {\it Fermi}-LAT…
GRB 190114C in the nuclear region of an interacting galaxy -- A detailed host analysis using ALMA, HST and VLT
A. de Ugarte Postigo, C. C. Thöne, S. Martın +28
GRB 190114C is the first GRB for which the detection of very-high energy emission up to the TeV range has been reported. It is still unclear whether environmental properties might…
Two New "Turn-off" Changing-look Active Galactic nuclei and Implication on "Partially Obscured" AGNs
J. Wang, D. W. Xu, Y. Wang +3
We here report a spectroscopic identification of two new changing-look AGNs (CL-AGNs): SDSS\,J104705.16+544405.8 and SDSS\,J120447.91+170256.8 both with a "turn-off" type transitio…
Narrow-line Seyfert 1 Galaxies and the M_BH - sigma Relation
S. Komossa, D. Xu
We have studied the location of narrow-line Seyfert 1 (NLS1) galaxies and broad-line Seyfert 1 (BLS1) galaxies on the M_BH - sigma relation of non-active galaxies. We find that NLS…
