Origin of the ring ellipticity in the black hole images of M87*
Rohan Dahale, Ilje Cho, Kotaro Moriyama +273
We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astro…
Multifrequency simultaneous VLBA view of the radio source 3C 111
V. Bartolini, D. Dallacasa, J. L. Gómez +3
Relativistic jets originating at the center of AGN are embedded in extreme environments with strong magnetic fields and high particle densities, which makes them a fundamental tool…
A multi-frequency study of sub-parsec jets with the Event Horizon Telescope
Jan Röder, Maciek Wielgus, Andrei P. Lobanov +287
The 2017 observing campaign of the Event Horizon Telescope (EHT) delivered the first very long baseline interferometry (VLBI) images at the observing frequency of 230 GHz, leading…
Demographics of black holes at 100 R scales: accretion flows, jets, and shadows
Dhanya G. Nair, Neil M. Nagar, Venkatessh Ramakrishnan +87
Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been…
Helical magnetic field structure in 3C 273. A Faraday rotation analysis using multi-frequency polarimetric VLBA data
Teresa Toscano, Sol N. Molina, José L. Gómez +12
We present a study on rotation measure (RM) of the quasar 3C 273. This analysis aims to discern the magnetic field structure and its temporal evolution. The quasar 3C 273 is one of…
Evolution, speed, and precession of the parsec-scale jet in the 3C 84 radio galaxy
M. Foschi, J. L. Gómez, A. Fuentes +3
We present high resolution images of the radio source 3C 84 at 43 GHz, from 121 observations conducted by the BEAM-ME monitoring program between 2010 and 2023. Imaging was performe…
The flaring activity of blazar AO 0235+164 during year 2021
Juan Escudero Pedrosa, Iván Agudo, Till Moritz +16
Context. The blazar AO 0235+164, located at redshift , has displayed interesting and repeating flaring activity in the past, the latest episodes occurring in 2008 and 2015.…
Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode
J. C. Algaba, M. Balokovic, S. Chandra +738
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…
