RAD@home citizen science discovery of an AGN spewing a large unipolar radio bubble onto its merging companion galaxy

Ananda Hota, Pratik Dabhade, Sravani Vaddi +8

AGN feedback during galaxy merger has been the most favoured model to explain black hole-galaxy co-evolution. However, how the AGN-driven jet/wind/radiation is coupled with the gas…

Pulsar Emission Beam Geometry of Radio Broadband Arecibo Sources

Timothy Olszanski, Joanna Rankin, Arun Venkataraman +1

We present radio pulsar emission beam analyses and models with the primary intent of examining pulsar beam geometry and physics over the broadest band of radio frequencies reasonab…

Nanohertz Gravitational Wave Astronomy during the SKA Era: An InPTA perspective

Bhal Chandra Joshi, Achamveedu Gopakumar, Arul Pandian +34

Decades long monitoring of millisecond pulsars, which exhibit highly stable rotational periods, in pulsar timing array experiments is on the threshold of discovering nanohertz stoc…

The Indian Pulsar Timing Array: First data release

Pratik Tarafdar, Nobleson K., Prerna Rana +35

We present the pulse arrival times and high-precision dispersion measure estimates for 14 millisecond pulsars observed simultaneously in the 300-500 MHz and 1260-1460 MHz frequency…

Evidence of surface heterogeneity on active asteroid (3200) Phaethon

Eric MacLennan, Sean Marshall, Mikael Granvik

Thermal infrared emission and thermophysical modeling techniques are powerful tools in deciphering the surface properties of asteroids. The near-Earth asteroid (3200) Phaethon is a…

A Parkes "Murriyang" Search for Pulsars and Transients in the Large Magellanic Cloud

Shinnosuke Hisano, Fronefield Crawford, Victoria Bonidie +6

We report on the latest results of a Parkes multibeam survey for pulsars and dispersed radio bursts in the Large Magellanic Cloud (LMC). We conducted both periodicity and single-pu…

The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background

J. Antoniadis, Z. Arzoumanian, S. Babak +123

We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…
