Radio Quasars in the Cosmic Dawn: A Spectroscopic Sample from the DESI Survey

Anniek J. Gloudemans, Jinyi Yang, David M. Alexander +55

We present the largest statistical spectroscopic sample of radio quasars at 4.7<z<6.7 to date. These have been selected from a dedicated Dark Energy Survey Instrument (DESI) target…

LOFAR follow-up of sources in the First LHAASO Catalogue

Maria Arias, Timothy Shimwell, Martin Hardcastle +1

The First LHAASO Catalogue lists 90 sources of very-high-energy gamma-ray emission, many without an established counterpart at other frequencies, reopening the question of which Ga…

Rapid radio variability in the blazar VLASS J04100139: Indication of a hidden population of weak radio jets at Cosmic Dawn

Silvia Belladitta, Eduardo Bañados, Anniek J. Gloudemans +7

Doppler boosting allows blazars to be detected out to high-, making them promising probes of the intergalactic medium through the 21 cm forest. We report 0.14411 GHz observat…

The magnetic field strength of a methane dwarf measured from its radio spectral cutoff

Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1

Brown dwarfs and gas-giant planets are expected to emit coherent radio emission via the electron cyclotron maser instability (ECMI) mechanism powered by non-thermal electrons in th…

Transient study using LoTSS -- framework development and preliminary results

Iris de Ruiter, Zachary S. Meyers, Antonia Rowlinson +3

We present a search for transient radio sources on time-scales of seconds to hours at 144 MHz using the LOFAR Two-metre Sky Survey (LoTSS). This search is conducted by examining sh…

Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction

H. K. Vedantham, J. R. Callingham, T. W. Shimwell +11

Low frequency (MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission…

Revisiting the Fanaroff-Riley dichotomy and radio-galaxy morphology with the LOFAR Two-Metre Sky Survey (LoTSS)

B. Mingo, J. H. Croston, M. J. Hardcastle +15

The relative positions of the high and low surface brightness regions of radio-loud active galaxies in the 3CR sample were found by Fanaroff and Riley to be correlated with their l…

An Automated Scalable Framework for Distributing Radio Astronomy Processing Across Clusters and Clouds

A. P. Mechev, J. B. R. Oonk, A. Danezi +5

The Low Frequency Array (LOFAR) radio telescope is an international aperture synthesis radio telescope used to study the Universe at low frequencies. One of the goals of the LOFAR…

Using rotation measure grids to detect cosmological magnetic fields -- a Bayesian approach

V. Vacca, N. Oppermann, T. Ensslin +17

Determining magnetic field properties in different environments of the cosmic large-scale structure as well as their evolution over redshift is a fundamental step toward uncovering…

Planck 2013 results. XXIX. The Planck catalogue of Sunyaev-Zeldovich sources: Addendum

Planck Collaboration, P. A. R. Ade, N. Aghanim +276

We update the all-sky Planck catalogue of 1227 clusters and cluster candidates (PSZ1) published in March 2013, derived from Sunyaev-Zeldovich (SZ) effect detections using the first…
