Multi-wavelength study of OT 081: broadband modelling of a transitional blazar

MAGIC Collaboration, H. Abe, S. Abe +270

OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…

Dynamical confirmation of a black hole in the X-ray transient Swift J1727.8-1613

D. Mata Sanchez, M. A. P. Torres, J. Casares +3

The X-ray transient Swift J1727.8-1613 ended its 10-month discovery outburst on June of 2024, when it reached an optical brightness comparable to pre-discovery magnitudes. With the…

Evidence for inflows and outflows in the nearby black hole transient Swift J1727.8-162

D. Mata Sánchez, T. Muñoz-Darias, M. Armas Padilla +2

We present 20 epochs of optical spectroscopy obtained with the GTC-10.4m telescope across the bright discovery outburst of the black hole candidate Swift J1727.8-162. The spectra c…

LeMMINGs IV: The X-ray properties of a statistically-complete sample of the nuclei in active and inactive galaxies from the Palomar sample

D. R. A. Williams, M. Pahari, R. D. Baldi +22

All 280 of the statistically-complete Palomar sample of nearby (<120 Mpc) galaxies dec > 20 degrees have been observed at 1.5 GHz as part of the LeMMINGs e-MERLIN legacy survey. He…

Southern African Large Telescope Spectroscopy of BL Lacs for the CTA project

E. Kasai, P. Goldoni, M. Backes +14

In the last two decades, very-high-energy gamma-ray astronomy has reached maturity: over 200 sources have been detected, both Galactic and extragalactic, by ground-based experiment…
