Dynamics and geometry of the inner sub-parsec-scale jet in 3C 279 observed with the Event Horizon Telescope

Hendrik Mueller, Sebastiano D. von Fellenberg, Ai-Ling Zeng +275

The 2021 Event Horizon Telescope observations resolve the innermost jet region of the blazar 3C279 with unprecedented detail. The reconstructed images consistently reveal a compact…

Ionization Structure and Metal Enrichment of the Galactic Center Minispiral Observed with JWST

Nicole M Ford, Mayura Balakrishnan, Sebastiano D. von Fellenberg +11

Sagittarius A* (Sgr A*) is the nearest quiescent supermassive black hole, and its proximity offers a unique opportunity to study its surrounding fuel supply. We leverage extensive…

Full-polarization millimeter wavelength variability of Sagittarius A* during the 2018 EHT campaign

Ezequiel Albentosa-Ruiz, Jasmin E. Washington, Nicola Marchili +272

Sagittarius A* (Srg A*), the supermassive black hole at the center of the Milky Way, provides a unique laboratory to study accretion dynamics and plasma processes near the event ho…

Hubble Study of the Proper Motion of HST-1 in the Jet of M87

Rameshan Thimmappa, Joey Neilsen, Daryl Haggard +2

The radio galaxy M87 is well known for its jet, which features a series of bright knots observable from radio to X-ray wavelengths. The most famous of these, HST-1, exhibits superl…

Photometric Constraints on Intermediate-mass Black Holes in the Galactic Centre

Tamojeet Roychowdhury, Sebastiano D. von Fellenberg, Joseph M. Michail +14

JWST/MIRI observations can place photometric limits on the presence of an intermediate-mass black hole (IMBH) near the Galactic Centre. The stellar complex IRS 13E, a co-moving con…

First polarization study of the M87 jet and active galactic nuclei at submillimeter wavelengths with ALMA

Ciriaco Goddi, Douglas F. Carlos

We present full-polarization observations at mm (345 GHz) conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) toward Messier 87 (M87) and seven other…
