First M87 Event Horizon Telescope Results and the Role of ALMA
Ciriaco Goddi, Geoff Crew, Violette Impellizzeri +41
In April 2019, the Event Horizon Telescope (EHT) collaboration revealed the first image of the candidate super-massive black hole (SMBH) at the centre of the giant elliptical galax…
Detection of pulses from the Vela pulsar at millimeter wavelengths with phased ALMA
Kuo Liu, Andre Young, Robert Wharton +20
We report on the first detection of pulsed radio emission from a radio pulsar with the ALMA telescope. The detection was made in the Band-3 frequency range (85-101 GHz) using ALMA…
The Pierre Auger Observatory: Contributions to the 36th International Cosmic Ray Conference (ICRC 2019)
The Pierre Auger Collaboration, A. Aab, P. Abreu +383
Contributions of the Pierre Auger Collaboration to the 36th International Cosmic Ray Conference (ICRC 2019), 24 July - 1 August 2019, Madison, Wisconsin, USA.
A Roadmap towards a Space-based Radio Telescope for Ultra-Low Frequency Radio Astronomy
M. J. Bentum, M. K. Verma, R. T. Rajan +10
The past two decades saw a renewed interest in low frequency radio astronomy, with a particular focus on frequencies above 30 MHz. However, at frequencies below 30 MHz, Earth-based…
Peering into the Dark (Ages) with Low-Frequency Space Interferometers
Leon Koopmans, Rennan Barkana, Mark Bentum +28
Neutral hydrogen pervades the infant Universe, and its redshifted 21-cm signal allows one to chart the Universe. This signal allows one to probe astrophysical processes such as the…
VLBI imaging of black holes via second moment regularization
S. Issaoun, M. D. Johnson, L. Blackburn +3
The imaging fidelity of the Event Horizon Telescope (EHT) is currently determined by its sparse baseline coverage. In particular, EHT coverage is dominated by long baselines, and i…
