AtLAST -- Determination of Halo Mass Density Profiles at kpc Scales through Magnification Bias
Joaquín González-Nuevo, Laura Bonavera, Juan Alberto Cano +9
Magnification bias, the lensing-induced modification of background source number counts, provides a uniquely powerful probe of the mass density profiles of galaxies and clusters do…
AtLAST -- Cosmology with submillimetre galaxies magnification bias
Laura Bonavera, Joaquin Gonzalez-Nuevo, Juan Alberto Cano +10
Magnification bias offers a uniquely powerful and independent route to cosmological information. As a gravitational-lensing observable, it probes galaxy-matter correlations without…
Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations
Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…
A deep ALMA Band 3 survey of HDFS/MUSE3D: Survey description and initial results
Hugo Messias, Laura Gomez, Harold Francke +7
(abridged) After more than 10yr of ALMA operations, the community interest in conducting deep, extra-galactic, millimetre surveys resulted in varying strategic compromises between…
Resolved Schmidt-Kennicutt relation in a binary hyperluminous infrared galaxy at
Jonathan S. Gómez, Hugo Messias, Neil M. Nagar +3
Hyperluminous infrared galaxies (HyLIRGs; SFRs up to about 1000 Msun yr-1), though rare, provide key constraints on galaxy evolution. H-ATLAS J084933.4+021443, a z = 2.41 binary Hy…
Molecular Gas in Major Mergers Hosting Dual and Single AGN at <10 kpc Nuclear Separations
Makoto A. Johnstone, Ezequiel Treister, Franz E. Bauer +24
We present high-resolution (50100 pc) Atacama Large Millimeter Array (ALMA) observations of CO(2-1) or CO(1-0) emission in seven local ( 0.05)…
HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo
P. Cox, K. M. Butler, C. R. Keeton +24
We present a study of HerS-3, a dusty star-forming galaxy at zspec = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy s…
Vz-GAL: Probing Cold Molecular Gas in Dusty Star-forming Galaxies at z=1-6
Prachi Prajapati, Dominik Riechers, Pierre Cox +20
We present the first results of Vz-GAL, a high-redshift CO(J=1-0) large survey with the Karl G. Jansky Very Large Array, targeting 92 Herschel-selected, infrared-luminous, dusty st…
An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: I. The properties of the 870 micron counterparts
E. Hatziminaoglou, H. Messias, R. Souza +6
(Abridged) Quasar studies with Herschel/SPIRE often report host luminosities ranging from 10^{12} to 10^{14} Lsun, suggestive of star formation rates (SFRs) of up to several thousa…
Hiding behind a curtain of dust: Gas and dust properties of an ultra-luminous strongly-lensed z = 3.75 galaxy behind the Milky Way disk
Belén Alcalde Pampliega, Kevin C. Harrington, Aristeidis Amvrosiadis +21
We present a detailed analysis of J154506, a strongly lensed submillimeter galaxy behind the Lupus-I molecular cloud, and characterisation of its physical properties using a combin…
First polarization study of the M87 jet and active galactic nuclei at submillimeter wavelengths with ALMA
Ciriaco Goddi, Douglas F. Carlos
We present full-polarization observations at mm (345 GHz) conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) toward Messier 87 (M87) and seven other r…
A panchromatic view of N2CLS GOODS-N: the evolution of the dust cosmic density since z~7
S. Berta, G. Lagache, A. Beelen +58
(abridged) To understand early star formation, it is essential to determine the dust mass budget of high-redshift galaxies. Sub-millimeter rest-frame emission, dominated by cold du…
