The LOFAR Two-Metre Sky Survey : VI. Optical identifications for the second data release
(2023-10-01)
The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of ∼5700 deg1. The high angular resolution of LOFAR with Dutch baselines (6 arcsec) allows us to carry out ...
Energy balance SED modelling can be effective at high redshifts regardless of UV-FIR offsets
(2023-10-01)
Recent works have suggested that energy balance spectral energy distribution (SED) fitting codes may be of limited use for studying high-redshift galaxies for which the observed ultraviolet and far-infrared emission are ...
Cosmic evolution of radio-AGN feedback: confronting models with data
(2023-08-30)
Radio-mode feedback is a key ingredient in galaxy formation and evolution models, required to reproduce the observed properties of massive galaxies in the local Universe. We study the cosmic evolution of radio-active ...
The LOFAR Two-metre Sky Survey: the radio view of the cosmic star formation history
(2023-05-26)
We present a detailed study of the cosmic star formation history over $90$ per cent of cosmic time ($0\lesssim z\lesssim4$), using deep, radio continuum observations that probe star formation activity independent of dust. ...
The LOFAR Two-metre Sky Survey Deep Fields Data Release 1 V. Survey description, source classifications and host galaxy properties
(2023-04-29)
Source classifications, stellar masses and star formation rates are presented for 80,000 radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey (LoTSS) Deep Fields, which represents the ...
The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
(2023-03-11)
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, ...
