Refining the prediction for OJ 287 next impact flare arrival epoch

Mauri J. Valtonen, Staszek Zola, A. Gopakumar +23

The bright blazar OJ~287 routinely parades high brightness bremsstrahlung flares which are explained as being a result of a secondary supermassive black hole (SMBH) impacting the a…

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…

Host galaxy magnitude of OJ 287 from its colours at minimum light

Mauri J. Valtonen, Lankeswar Dey, S. Zola +54

OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…

Unravelling the Innermost Jet Structure of OJ 287 with the First GMVA+ALMA Observations

Guang-Yao Zhao, Jose L. Gomez, Antonio Fuentes +33

We present the first very-long-baseline interferometric (VLBI) observations of the blazar OJ287 carried out jointly with the Global Millimeter VLBI Array (GMVA) and the phased Atac…
