A NOEMA molecular line scan of the Hubble Deep Field North: Improved constraints on the CO luminosity functions and cosmic density of molecular gas

Leindert A. Boogaard, Roberto Decarli, Fabian Walter +9

We present measurements of the CO luminosity functions (LFs) and the evolution of the cosmic molecular gas density out to z~6 based on an 8.5 arcmin^2 spectral scan survey at 3mm o…

Unprecedented change in the position of four radio sources

Oleg Titov, Sándor Frey, Sébastien Lambert +7

Astrometric positions of radio-emitting active galactic nuclei (AGNs) can be determined with sub-milliarcsec accuracy using very long baseline interferometry (VLBI). The usually sm…

The GLEAM 4-Jy (G4Jy) Sample: I. Definition and the catalogue

Sarah V. White, Thomas M. O. Franzen, Chris J. Riseley +21

The Murchison Widefield Array (MWA) has observed the entire southern sky (Declination, 30 deg) at low radio-frequencies, over the range 72-231 MHz. These observations constitu…

The GLEAM 4-Jy (G4Jy) Sample: II. Host-galaxy identification for individual sources

Sarah V. White, Thomas M. O. Franzen, Chris J. Riseley +20

The entire southern sky (Declination, 30 deg) has been observed using the Murchison Widefield Array (MWA), which provides radio imaging of 2-arcmin resolution at low fre…

Spica and the annual cycle of PKS B1322-110 scintillations

Hayley Bignall, Cormac Reynolds, Jamie Stevens +9

PKS B1322-110 is a radio quasar that is located only 8.5' in angular separation from the bright B star Spica. It exhibits intra-day variability in its flux density at GHz frequenci…
