HI content at cosmic noon -- a millimeter-wavelength perspective
Hugo Messias, Andrea Guerrero, Neil Nagar +4
In order to understand galaxy growth evolution, it is critical to constrain the evolution of its building block: gas. Mostly comprised by Hydrogen in its neutral (HI) and molecular…
First Sagittarius A* Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole in the Center of the Milky Way
The Event Horizon Telescope Collaboration
We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A), the Galactic center source associated with a supermassive black hole. These observati…
Observations of Low and Intermediate Spectral Peak Blazars with the Imaging X-ray Polarimetry Explorer
Herman L. Marshall, Ioannis Liodakis, Alan P. Marscher +145
We present X-ray polarimetry observations from the Imaging X-ray Polarimetry Explorer (IXPE) of three low spectral peak and one intermediate spectral peak blazars, namely 3C 273, 3…
Selection of powerful radio galaxies with machine learning
R. Carvajal, I. Matute, J. Afonso +12
We developed and trained a pipeline of three machine learning (ML) models than can predict which sources are more likely to be an AGN and to be detected in specific radio surveys.…
Tracing obscured galaxy build-up at high redshift using deep radio surveys
Stergios Amarantidis, Jose Afonso, Israel Matute +5
A fundamental question of extra-galactic astronomy that is yet to be fully understood, concerns the evolution of the star formation rate (SFR) and supermassive black hole (SMBH) ac…
SUNRISE: The rich molecular inventory of high-redshift dusty galaxies revealed by broadband spectral line surveys
Chentao Yang, Alain Omont, Sergio Martín +21
Understanding the nature of high- dusty galaxies requires a comprehensive view of their ISM and molecular complexity. However, the molecular ISM at high- is commonly studied…
z-GAL -- A NOEMA spectroscopic redshift survey of bright Herschel galaxies: [III] Physical properties
S. Berta, F. Stanley, D. Ismail +35
The z-GAL survey observed 137 bright Herschel-selected targets with the IRAM NOrthern Extended Millimeter Array, with the aim to measure their redshift and study their properties.…
z-GAL -- A NOEMA spectroscopic redshift survey of bright Herschel galaxies: [II] Dust properties
D. Ismail, A. Beelen, V. Buat +34
(Abridged) We present the dust properties of 125 bright Herschel galaxies selected from the z-GAL survey. The large instantaneous bandwidth of NOEMA provides an exquisite sampling…
z-GAL -- A NOEMA spectroscopic redshift survey of bright Herschel galaxies: [I] Overview
P. Cox, R. Neri, S. Berta +35
(Abridged) Using the IRAM NOEMA interferometer, we measures the redshifts of 126 bright galaxies detected in the Herschel H-ATLAS, HeLMS, and HerS surveys. We report reliable spect…
ALMA High-Level Data Products: Submillimetre counterparts of SDSS quasars in the ALMA footprint
A. Wong, E. Hatziminaoglou, A. Borkar +5
The Atacama Large Millimetre/submillimetre Array (ALMA) is the world's most advanced radio interferometric facility, producing science data with an average rate of about 1 TB per d…
A ring-like accretion structure in M87 connecting its black hole and jet
Ru-Sen Lu, Keiichi Asada, Thomas P. Krichbaum +118
The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3…
Bright Extragalactic ALMA Redshift Survey (BEARS) III: Detailed study of emission lines from 71 Herschel targets
M. Hagimoto, T. J. L. C. Bakx, S. Serjeant +55
We analyse the molecular and atomic emission lines of 71 bright Herschel-selected galaxies between redshifts 1.4 to 4.6 detected by the Atacama Large Millimetre/submillimetre Array…
The Bright Extragalactic ALMA Redshift Survey (BEARS) II: Millimetre photometry of gravitational lens candidates
G. J. Bendo, S. A. Urquhart, S. Serjeant +49
We present 101 and 151 GHz ALMA continuum images for 85 fields selected from Herschel observations that have 500 micron flux densities >80 mJy and 250-500 micron colours consistent…
