Spectropolarimetry of A Nuclear Transient AT2023clx: Revealing The Geometrical Alignment between The Transient Outflow and The Nuclear Dusty Region
Kohki Uno, Keiichi Maeda, Takashi Nagao +10
AT2023clx, which occurred in NGC3799 with a Low-Ionization Nuclear Emission-Line Region (LINER), is one of the most nearby nuclear transients classified as a tidal disruption event…
Main-oval auroral emission from a T6 brown dwarf: observations, modeling, and astrometry
J. C. Guirado, J. B. Climent, J. D. Bergasa +3
From a series of 5 GHz VLBA radio observations taken over 1-yr span, we present the detection of compact highly-polarized radio emission from the T6 brown dwarf WISE J112254.72+255…
Searching for star-planet interactions in GJ 486 at radio wavelengths with the uGMRT
L. Peña-Moñino, M. Pérez-Torres, D. Kansabanik +14
We search for radio emission from star-planet interactions in the M-dwarf system GJ~486, which hosts an Earth-like planet. We observed the GJ~486 system with the upgraded Giant Met…
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Ziteng Wang, Nanda Rea, Tong Bao +46
Recently, a class of long-period radio transients (LPTs) has been discovered, exhibiting emission on timescales thousands of times longer than radio pulsars. Several models had bee…
A multi-frequency, multi-epoch radio continuum study of the Arches cluster with the VLA
M. Cano-González, R. Schödel, A. Alberdi +4
The Arches cluster, one of the most massive clusters in the Milky Way, is located about 30 pc in projection from the central massive black hole. With its high mass, young age, and…
The expansion of the GRB 221009A afterglow
S. Giarratana, O. S. Salafia, M. Giroletti +14
We observed -ray burst (GRB) 221009A using very long baseline interferomety (VLBI) with the European VLBI Network (EVN) and the Very Long Baseline Array (VLBA), over a period s…
