Multiwavelength Classification of Chandra Sources in Omega Centauri

Steven Chen, Oleg Kargaltsev, Jeremy Hare +4

We present a comprehensive study of X-ray sources in the globular cluster NGC 5139 to date. Over 200 Chandra sources are cross-matched to multiwavelength catalogs from HST, JWST, a…

Mining the time axis with TRON - III. Discovery of a nulling pulsar towards the SMC with MeerKAT

T. Blecher, M. Geyer, O. M. Smirnov +21

We report on the discovery of a nulling pulsar, PSR J00527551, in archival MeerKAT L-band observations of the Small Magellanic Cloud (SMC). The discovery was made using the imag…

The VLA and High-Frequency SETI: Expanding the Search for Life

Talon Myburgh, Noah Stiegler, Chenoa D. Tremblay +2

The Commensal Open-Source Multimode Interferometer Cluster (COSMIC) runs software that searches for technologies elsewhere in the Universe ("technosignatures") using the Karl G. Ja…

A search for narrowband technosignatures from LTT 3780 with the Allen Telescope Array and the Karl G. Jansky Very Large Array

Chenoa D. Tremblay, Sofia Z. Sheikh, Vishal Gajjar +9

The LTT3780 system hosts two known exoplanets-LTT3780b, a rocky super-Earth, and LTT3780c, a temperate sub-Neptune-orbiting a nearby M dwarf on opposite sides of the radius valley.…

Radio Activity from the Rapidly Rotating T dwarf 2MASS 2228-4310

Kelvin Wandia, Michael A. Garrett, Aaron Golden +7

We present the detection of 2MASS J22282889-4310262 (2M2228), a T6/T6.5 brown dwarf, using the Karl G. Jansky Very Large Array (VLA) archival data observed at C band (4-8 GHz) over…

Mining the time axis with TRON. I. Millisecond pulsars in Omega Centauri, Terzan 5 and 47 Tucanae detected through MeerKAT interferometric imaging

Oleg M. Smirnov, Ian Heywood, Marisa Geyer +13

Medium-timescale (minutes to hours) radio transients are a relatively unexplored population. The wide field-of-view and high instantaneous sensitivity of instruments such as MeerKA…

COSMIC's Large-Scale Search for Technosignatures during the VLA sky Survey: Survey Description and First Results

Chenoa D. Tremblay, Jared Sofair, Lucy Steffes +9

Developing algorithms to search through data efficiently is a challenging part of searching for signs of technology beyond our solar system. We have built a digital signal processi…

Mining the time axis with TRON. II. MeerKAT detects a stellar radio flare from a distant RS CVn candidate

Oleg M. Smirnov, Aaron Golden, Talon Myburgh +14

Medium-timescale (minutes to hours) radio transients are a relatively unexplored population. The wide field-of-view and high instantaneous sensitivity of instruments such as MeerKA…

COSMIC: An Ethernet-based Commensal, Multimode Digital Backend on the Karl G. Jansky Very Large Array for the Search for Extraterrestrial Intelligence

Chenoa D. Tremblay, Savin Shynu Varghese, Jack Hickish +14

The primary goal of the search for extraterrestrial intelligence (SETI) is to gain an understanding of the prevalence of technologically advanced beings (organic or inorganic) in t…

MeerKAT-16 HI observation of the dIrr galaxy WLM

Roger Ianjamasimanana, Brenda Namumba, Athanaseus J. T. Ramaila +19

We present observations and models of the kinematics and the distribution of the neutral hydrogen (HI) in the isolated dwarf irregular galaxy, Wolf-Lundmark-Melotte (WLM). We obser…
