Comparing the size evolution of GRB 221009A with afterglow models
S. Giarratana, O. S. Salafia, B. Marcote +10
We present very long baseline interferometry (VLBI) observations of GRB221009A obtained with the global-VLBI network at 5 GHz between 231 and 750 days after the burst. The quality…
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…
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…
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…
Supernova environments in J-PLUS. Normalized Cumulative Rank distributions and stellar population synthesis, combining narrow- and broad-band filters
Raul González-Díaz, Lluís Galbany, Tuomas Kangas +26
We study the local environmental properties of 418 supernovae (SNe) of all types using data from the Javalambre Photometric Local Universe Survey (J-PLUS), which includes 5 broad-…
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 sp…
Panning for gold, but finding helium: discovery of the ultra-stripped supernova SN2019wxt from gravitational-wave follow-up observations
I. Agudo, L. Amati, T. An +96
We present the results from multi-wavelength observations of a transient discovered during the follow-up of S191213g, a gravitational wave (GW) event reported by the LIGO-Virgo Col…
The Close AGN Reference Survey (CARS): Comparative analysis of the structural properties of star-forming and non-star-forming galaxy bars
Justus Neumann, Dimitri A. Gadotti, Lutz Wisotzki +12
The absence of star formation in the bar region that has been reported for some galaxies can theoretically be explained by shear. However, it is not clear how star-forming (SF) bar…
Evolution of the progenitors of SNe 1993J and 2011dh revealed through late time radio and X-ray studies
Esha Kundu, Peter Lundqvist, Elena Sorokina +6
We perform hydrodynamical simulations of the interaction between supernova (SN) ejecta and circumstellar medium (CSM) for SN 1993J and SN 2011dh, and calculate the radio and X-ray…
Constraining magnetic field amplification in SN shocks using radio observations of SNe 2011fe and 2014J
Esha Kundu, Peter Lundqvist, Miguel A. Pérez-Torres +2
We modeled the radio non-detection of two Type Ia supernovae (SNe) 2011fe and 2014J considering synchrotron emission from the interaction between SN ejecta and the circumstellar me…
