First fast radio burst search campaign at the Argentine Institute of Radio Astronomy
Carlos O. Lousto, Harsh Prajapati, Ezequiel Zubieta +9
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…
Antikick Relation in High-Energy Head-On Collisions of Spinning Black Holes
Carlos O. Lousto, James Healy, Alessandro Ciarfella +1
The paper studies head‑on collisions of equal‑mass spinning black holes at relativistic speeds, analyzing the recoil (kick) and antikick using numerical simulations and analytical…
The Fifth RIT Catalog of Binary Black Hole Simulations: Multiple-Resolution Studies of Eccentric Orbits
Giuseppe Ficarra, James Healy, Carlos O. Lousto
This fifth release of the RIT public catalog of numerical relativity binary black hole waveforms http://ccrg.rit.edu/~RITCatalog introduces an additional 248 configurations, priori…
Parameter Estimation with Targeted Eccentric Numerical-Relativity Simulations for GW200208_22 and GW190620
Patricia McMillin, Katelyn J. Wagner, Giuseppe Ficarra +2
We have analyzed LVK gravitational wave events that show some evidence of eccentricity from TEOBResumS modeling parameter estimations and have confronted them independently with fu…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
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…
