eDIG-CHANGES I: Extended Hα Emission from the Extraplanar Diffuse Ionized Gas (eDIG) around CHANG-ES Galaxies

Li-Yuan Lu, Jiang-Tao Li, Carlos J. Vargas +14

The extraplanar diffuse ionized gas (eDIG) represents the cool/warm ionized gas reservoir around galaxies. We present a spatial analysis of H images of 22 nearby edge-on spiral…

HALOGAS: Strong Constraints on the Neutral Gas Reservoir and Accretion Rate in Nearby Spiral Galaxies

P. Kamphuis, E. Jütte, G. H. Heald +11

Galaxies in the local Universe are thought to require ongoing replenishment of their gas reservoir in order to maintain the observed star formation rates. Cosmological simulations…

Collimation of the kiloparsec-scale radio jets in NGC 2663

Velibor Velović, M. D. Filipović, L. Barnes +25

We present the discovery of highly-collimated radio jets spanning a total of 355 kpc around the nearby elliptical galaxy NGC 2663, and the possible first detection of recollimation…

The redshift evolution of extragalactic magnetic fields

Valentin Pomakov, Shane O'Sullivan, Marcus Bruggen +7

Faraday rotation studies of distant radio sources can constrain the evolution and the origin of cosmic magnetism. We use data from the LOFAR Two Metre Sky Survey: Data Release 2 (L…

GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) I: Survey Description and Initial Data Release

Natasha Hurley-Walker, Timothy J. Galvin, Stefan W. Duchesne +15

We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72 - 231 MHz and Declinations south of have been performed with the Mur…

The GLEAMing of the first supermassive black holes: II. A new sample of high-redshift radio galaxy candidates

J. W. Broderick, G. Drouart, N. Seymour +27

While unobscured and radio-quiet active galactic nuclei are regularly being found at redshifts , their obscured and radio-loud counterparts remain elusive. We build upon our…

Nearby galaxies in LoTSS-DR2: insights into the non-linearity of the radio-SFR relation

V. Heesen, M. Staffehl, A. Basu +24

Context. Cosmic rays and magnetic fields are key ingredients in galaxy evolution, regulating both stellar feedback and star formation. Their properties can be studied with low-freq…

Deep ASKAP EMU Survey of the GAMA23 field: Properties of radio sources

Gülay Gürkan, I. Prandoni, A. O'Brien +19

We present the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the Galaxy and Mass Assembly (GAMA)-23h field. The survey was carried out at 887.5 MHz and cover…

Searching for pulsars associated with polarised point sources using LOFAR: Initial discoveries from the TULIPP project

C. Sobey, C. G. Bassa, S. P. O'Sullivan +15

Discovering radio pulsars, particularly millisecond pulsars (MSPs), is important for a range of astrophysical applications, such as testing theories of gravity or probing the magne…

The LOFAR Two-metre Sky Survey -- V. Second data release

T. W. Shimwell, M. J. Hardcastle, C. Tasse +103

In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…

Magnetic field strength in cosmic web filaments

E. Carretti, V. Vacca, S. P. O'Sullivan +8

We used the Rotation Measure (RM) catalogue derived from the LOFAR Two-metre Sky Survey Data Release 2 (LoTSS DR2) at 144-MHz to measure the evolution with redshift of the extragal…
