A team led by astronomers in the Netherlands have confirmed a repeating #FRB source to be linked to a potential ‘hypernebula’ – a dense and highly magnetised cloud of plasma that is illuminated by a powerful but still mysterious source. #VLBI t.ly/pBswn

In our recent publication we confirmed a second repeating FRB source to be linked with a compact radio object. Amazing teamwork with the Astroflash⚡️and our international collaborators Navin Sridhar and Tarraneh Eftekhari. doi.org/10.3847/2041-8… via AAS Publishing

New paper arxiv.org/abs/2404.08048 led by Nikhil. We examine the claimed link between GRB 201006 and the FRB that appeared ~1hr later. We think 1. The association is not statistically robust, 2. The remnant is unlikely to be a long-lived neutron star; instead, likely a black hole.

New paper, led by Vic! What's powering the off-nuclear persistent radio sources seen in nearby dwarf galaxies? Wandering large, massive black holes or powerful smaller black holes/neutron stars? These emissions resemble the persistent radio counterparts seen from FRB sources.

Academic updates: -- It was an honor to learn from and work with my advisors Brian Metzger Brian Metzger and Lorenzo Sironi during my PhD Columbia University; I can't thank them enough! -- I will be joining Stanford University KIPAC this Fall 2024 for my postdoctoral fellowship SCEECS.

New paper! arxiv.org/abs/2409.11533 Led by Adaeze, in this paper, we report 2 new persistent radio source candidates associated with fast radio bursts (20181030A and 20190417A)! We also discuss the engines (magnetar, accreting hypernebulae, etc.) that could potentially power them.

We're having a lecture this week about one of the biggest unsolved mysteries in the universe: short, intense radio flashes from space called Fast Radio Bursts (FRBs)! Come and watch KIPAC Postdoc Navin Sridhar discuss possible sources of FRBs this week! bit.ly/frb-dec5

New paper, led by student Sanya: arxiv.org/abs/2501.00979! tl;dr: In relativistic reconnection, the initial stages of particle energization happen mostly in 'non-ideal' regions where electric field dominates over magnetic field; relevant for black hole/neutron star magnetospheres.

A new study published today by Navin Sridhar and other collaborators reveals the sheath of black hole jets could be the long-sought source of comptonising corona responsible for producing hard X-rays utiziling GRRMHD.
