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…

HI line observations of 290 evolved stars made with the Nancay Radio Telescope -- I. Data

E. Gerard, W. van Driel, L. D. Matthews +3

We present a compendium of HI 21-cm line observations of circumstellar envelopes (CSEs) of 290 evolved stars, mostly (~84%) on the asymptotic giant branch (AGB), made with the 100m…

Detection of Rydberg lines from the atmosphere of Betelgeuse

W. R. F. Dent, G. Harper, A. M. S. Richards +2

Emission lines from Rydberg transitions are detected for the first time from a region close to the surface of Betelgeuse. The H30 line is observed at 231.905 GHz, with a FWHM ~4…
