First detection of C2H+ in the interstellar medium
Arshia M. Jacob, Karl M. Menten, Sandra Brünken +10
Despite the detection of nearly 350 molecules in the interstellar medium, almost half of which are carbon chains, the pathways that build molecular complexity remain poorly underst…
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…
Kinetic temperature of massive star-forming molecular clumps measured with formaldehyde VI. The photodissociation region M17SW
X. Zhao, X. D. Tang, C. Henkel +20
The kinetic temperature structure of the photodissociation region M17SW was mapped using the IRAM 30 m telescope. This mapping employed the para-H2CO triplet (J(KaKc) = 303-202, 32…
An updated model for the Perseus Spiral Arm from Trigonometric Parallax and 3-dimensional kinematic distances of distant massive stars
Lucas J. Hyland, Mark J. Reid, Simon P. Ellingsen +3
We report trigonometric parallaxes and proper motions for three water masers and one methanol maser obtained with the VLBA as part of the BeSSeL Survey. Incorporating these paralla…
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…
Exploring the interplay between molecular and ionized gas in HII regions
S. Khan, A. M. Jacob, M. R. Rugel +8
We aim to constrain the kinetic temperature and H volume density of massive star-forming clumps associated with HII regions using multiple para-HCO transitions. In addition…
