Testing Gravity with Binary Pulsars in the SKA Era
V. Venkatraman Krishnan, L. Shao, V. Balakrishnan +21
Binary (and trinary) radio pulsars are natural laboratories in space for understanding gravity in the strong field regime, with many unique and precise tests carried out so far, in…
Inflationary interpretation of the gravitational-wave signal in the European Pulsar Timing Array DR2 with constraints
Philippe Turgeon, Chiara Caprini, Anton Chudaykin +5
The second data release of the European Pulsar Timing Array (EPTA) collaboration provides evidence for the presence of a gravitational-wave (GW) background. In this work, we explor…
Constraints on Einstein-aether gravity from the precision timing of PSR J1738+0333
Massimo Vaglio, Amodio Carleo, Abhimanyu Susobhanan +5
We constrain Einstein-aether gravity -- a Lorentz-violating extension of General Relativity in which a dynamical, unit timelike vector field selects a preferred frame -- using upda…

Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21
We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…
The First High Frequency Technosignature Search Survey with the Sardinia Radio Telescope
Lorenzo Manunza, Alice Vendrame, Luca Pizzuto +30
The quest for radio signals from technologically-advanced extraterrestrial intelligence has traditionally concentrated on the vicinity of 1.4 GHz. In this paper, we extend the sear…
