Phase-resolved X-ray spectroscopy of the Vela pulsar with NICER observations
E. Zubieta, F. García, S. del Palacio +2
PSR J0835-4510 (a.k.a. the Vela pulsar) is the best studied pulsar in the Southern hemisphere given its high radio brightness and large glitch activity. However, its X-ray brightne…
The influence of free-free absorption on the radio spectrum of Particle-Accelerating Colliding-Wind Binaries
Michaël De Becker, Agustina Belen Blanco, Mathilde Tasseroul +4
The study of massive stars in binary and higher-multiplicity systems that participate in particle acceleration is a key topic at the crossroads of massive star physics, shock physi…
Radio Emission with Dust: A Bow-Shock Interpretation for the TDE Candidate AT 2019avd
Shuyuan Wei, Yanan Wang, Guobin Mou +5
Forward shocks produced by interactions between a single ejected blob and the circumnuclear medium (CNM) around a supermassive black hole are widely invoked to explain radio emissi…
Single-pulse reanalysis of the 2024 Vela glitch and new observations of PSR~J04374715 and PSR~J16444559
Carlos O. Lousto, Ruby Shrestha, Ezequiel Zubieta +6
The Pulsar Monitoring in Argentina (PuMA) collaboration systematically monitors southern glitching pulsars, maintaining high-cadence single-pulse records of the Vela pulsar. We pre…
First fast radio burst search campaign at the Argentine Institute of Radio Astronomy
Carlos O. Lousto, Harsh Prajapati, Ezequiel Zubieta +7
Fast radio bursts (FRBs) are intense millisecond-duration radio transients of extragalactic origin whose physical nature remains under active investigation, and which also serve as…
Enabling population studies on wind-driven Galactic binary systems
B. Marcote, P. Benaglia, V. Bosch-Ramon +8
Galactic binaries driven by stellar wind shocks, such as colliding wind binaries (CWBs) and gamma-ray binaries (gBs), harbor one of the most efficient particle acceleration engines…
Correlation Between Hard X-Ray and Cosmic Neutrino Sources: From Obscured AGN to Blazars
Emma Kun, Imre Bartos, Claudio Ricci +5
The origin of high-energy astrophysical neutrinos remains a key open question in multimessenger astrophysics. A correlation between unabsorbed hard X-ray and high-energy neutrino l…
The Emerging Population of High-energy Emitting Radio Galaxies
G. Bruni, V. S. Paliya, D. J. Saikia +22
High-energy emission from radio galaxies provides a unique laboratory to study the connection between accretion, jet formation, and particle acceleration in active galactic nuclei…
The Millimeter/X-ray Relation in Rapidly Accreting Supermassive Black Holes at
Sophie M. Venselaar, Claudio Ricci, Santiago Del Palacio +12
A tight correlation between nuclear millimeter and X-ray emission has recently been found in nearby () and low-Eddington ratio () radio-quiet Active Ga…
Upstream neutrino production and delayed jet emission in the blazar GB6 J1542+6129
Emma Kun, Imre Bartos, Breshna Hadi +7
We present a multimessenger case study of the blazar GB6 J1542+6129, examining whether its multiwavelength behavior is consistent with neutrino production in a compact region near…
Giant radio pulses in the magnetar XTE J1810-197 detected with the IAR's telescopes
S. B. Araujo Furlan, G. E. Romero, E. Zubieta +4
[...] We observed XTE J1810-197 between 29 September 2022 and 14 July 2023 with the radio telescopes at the Argentine Institute of Radioastronomy (IAR). We searched for single puls…
