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…

Superorbital variability in the quiescent black hole X-ray transient A0620-00

Enzo A. Saavedra, Roi Alonso, Teo Muñoz-Darias +10

Quiescent black hole low-mass X-ray binaries provide a key setting for probing accretion physics at low luminosities. A0620-00, the archetypal system in this class, has remained in…

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…

Spectral properties of the neutron star low-mass X-ray binary 4U 1636-53, XTE J1739-285 and MAXI J1816-195

Zhenyan Fei, Ming Lyu, Guobao Zhang +2

We investigated simultaneous NICER plus NuSTAR observations of three neutron star low-mass X-ray binary 4U 1636-53, XTE J1739-285 and MAXI J1816-195 using the latest reflection mod…

Geometry of the comptonization region of MAXI J1348630 through type-C quasi-periodic oscillations with NICER

Kevin Alabarta, Mariano Méndez, Federico García +5

We use the rms and lag spectra of the type-C quasi-periodic oscillation (QPO) to study the properties of the Comptonisation region (aka corona) during the low/hard and hard-interme…
