Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
PSR J0537-6910: Exponential recoveries detected for 12 glitches
E. Zubieta, C. M. Espinoza, D. Antonopoulou +4
Pulsar glitches are unresolved increments of the rotation rate that sometimes trigger an enhancement of the spin-down rate. On occasions, the augmented spin-down decays gradually i…
A consistent radio to sub-mm pc-scale study of the nucleus of NGC 1068
Isaac M. Mutie, Santiago del Palacio, Robert J. Beswick +5
The origin of radio emission in radio-quiet (RQ) AGN remains a long-standing mystery. We present a detailed study of the cm to sub-mm emission from the nucleus of the nearby protot…
Study of the 2024 major Vela glitch at the Argentine Institute of Radioastronomy
Ezequiel Zubieta, Ryan Missel, Susana B. Araujo Furlan +6
We report here on new results of the systematic monitoring of southern glitching pulsars at the Argentine Institute of Radioastronomy. In particular, we study in this work the new…
High-sensitivity radio study of the non-thermal stellar bow shock EB27
Paula Benaglia, Santiago del Palacio, Christopher Hales +1
We present a deep radio-polarimetric observation of the stellar bow shock EB27 associated to the massive star BD+43 3654. This is the only stellar bow shock confirmed to have non-t…
PSR J0437-4715: The Argentine Institute of Radioastronomy 2019-2020 Observational Campaign
V. Sosa Fiscella, S. del Palacio, L. Combi +11
The Argentine Institute of Radio astronomy (IAR) is equipped with two single-dish 30-m radio antennas capable of performing daily observations of pulsars and radio transients in th…
The gamma-ray / infrared luminosity correlation of star-forming galaxies
P. Kornecki, L. J. Pellizza, S. del Palacio +3
Context. Near a dozen star-forming galaxies have been detected in gamma-rays by the Fermi observatory in the last decade. A remarkable property of this sample is the quasi-linear r…
Upgraded antennas for pulsar observations in the Argentine Institute of Radio astronomy
G. Gancio, C. O. Lousto, L. Combi +9
The Argentine Institute of Radio astronomy (IAR) is equipped with two single-dish 30mts radio antennas capable of performing daily observations of pulsars and radio transients in t…
Gamma rays from jets interacting with BLR clouds in blazars
S. del Palacio, V. Bosch-Ramon, G. E. Romero
The innermost parts of powerful jets in active galactic nuclei are surrounded by dense, high-velocity clouds from the broad-line region, which may penetrate into the jet and lead t…
Multi-zone non-thermal radiative model for stellar bowshocks
S. del Palacio, V. Bosch-Ramon, A. L. Müller +1
Context: Runaway stars produce bowshocks that are usually observed at infrared (IR) wavelengths. Non-thermal radio emission has been detected so far only from the bowshock of BD+43…
