Searching in HI for Massive Low Surface Brightness Galaxies: Samples from HyperLeda and the UGC

K. O'Neil, Stephan E. Schneider, W. van Driel +4

A search has been made for 21 cm HI line emission in a total of 350 unique galaxies from two samples whose optical properties indicate they may be massive The first consists of 241…

LOFAR imaging of Cygnus A -- Direct detection of a turnover in the hotspot radio spectra

J. P. McKean, L. E. H. Godfrey, S. Vegetti +75

The low-frequency radio spectra of the hotspots within powerful radio galaxies can provide valuable information about the physical processes operating at the site of the jet termin…

A comparative analysis of Galactic extinction at low Galactic latitudes

A. C. Schröder, W. van Driel, R. C. Kraan-Korteweg

We use near-infrared (J-K)-colours of bright 2MASS galaxies, measured within a 7"-radius aperture, to calibrate the Schlegel et al. (1998) DIRBE/IRAS Galactic extinction map at low…

LeMMINGs. II. The e-MERLIN legacy survey of nearby galaxies. The deepest radio view of the Palomar sample on parsec scale

R. D. Baldi, D. R. A. Williams, I. M. McHardy +30

We present the second data release of high-resolution ( arcsec) 1.5-GHz radio images of 177 nearby galaxies from the Palomar sample, observed with the e-MERLIN array, as p…

Radio spectral properties and jet duty cycle in the restarted radio galaxy 3C388

M. Brienza, R. Morganti, J. Harwood +9

Restarted radio galaxies represent a unique tool to investigate the duty cycle of the jet activity in Active Galactic Nuclei. Due to a sharp discontinuity of the GHz spectral index…

First detection of frequency-dependent, time-variable dispersion measures

J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +11

Context. High-precision pulsar-timing experiments are affected by temporal variations of the Dispersion Measure (DM), which are related to spatial variations in the interstellar el…
