The X-ray Astrophysics Group (GARX) is a group of astrophysicists based at the Argentine Institute of Radioastronomy (IAR) and the National University of La Plata (UNLP). GARX is formed by Researchers, Postdocs, PhD and M. Sc. students supported by the Argentine Research Council (CONICET), with multiple national and international collaborators. Their research mainly focuses on X-ray binaries, accreting compact objects, such as neutron stars and black holes, and their extended counterparts, supernova remnants.
high-mass and low-mass X-ray binaries; catalogs; accretion/ejection; variability; spectral-timing; quasi-periodic oscillations; highly-absorbed systems; microquasars
thermal emission; chemical abundances; shocks; particle-acceleration; synchrotron emission; radio continuum and gamma-ray emission.
formation and evolution of high-mass X-ray binaries; connection to sgHMXBs and SFXTs; neutron-star kicks; binary compact-objects progenitors; gravitational wave coalesces.

GARX supports open-source friendly-coding philosophy. Most of our codes related to X-ray data analysis, spectral-timing models and binary evolution, can be accessed through version-control portals like GitHub. Here we list some of the codes developed and maintained by members of our group and their collaborators.
Our X-ray Astrophysics Group (GARX) develops its activities at the Argentine Institute of Radioastronomy (IAR) and the National University of La Plata (UNLP), Argentina, connected to the Group of Relativistic Astrophysics and Radioastronomy (GARRA).
