High Frequency Wideband Study of FRB 20240114A with the Allen Telescope Array
Param Joshi, Vishal Gajjar, Joel Earwicker +14
We present a high-frequency, wideband observing campaign of the hyperactive repeating fast radio burst FRB 20240114A with the Allen Telescope Array. Between 27 January and 29 Octob…
A Search for Radio Technosignatures from Interstellar Object 3I/ATLAS with the Allen Telescope Array
Sofia Z. Sheikh, Valeria Garcia Lopez, Isabel Gerrard +12
In 2025 July, the third-ever interstellar object, 3I/ATLAS, was discovered on its ingress into the Solar System. Similar to the NASA Voyager missions sent in 1977, science probes b…
On the Deepest Search for Galactic Center Pulsars and an Examination of an Intriguing Millisecond Pulsar Candidate
Karen I. Perez, Vishal Gajjar, Slavko Bogdanov +6
We report results of one of the most sensitive pulsar surveys to date targeting the innermost region of the Galactic Center (GC) using the Robert C. Byrd Green Bank Telescope (GBT)…
Noisy Timing Behavior is a Feature of Central Compact Object Pulsars
K. I. Perez, E. V. Gotthelf, J. P. Halpern
We present a timing study of the three known central compact object (CCO) pulsars, isolated cooling neutron stars in supernova remnants, using Chandra, XMM-Newton and NICER observa…
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…
