Scaling laws of dust, H i gas and metal mass with stellar mass, specific star formation rate and metallicity are crucial to our understanding of the buildup of galaxies through their enrichment with metals and dust. In ...

The curious activity in the nucleus of NGC 4151 : jet interaction causing variability?

Williams, D. R. A.; Baldi, R. D.; McHardy, I. M.; Beswick, R. J.; Panessa, F.; May, D.; Moldón, J.; Argo, M. K.; Bruni, G.; Dullo, B. T.; Knapen, J. H.; Brinks, E.; Fenech, D. M.; Mundell, C. G.; Muxlow, T. W. B.; Pahari, M.; Westcott, J. (2020-05-04)

A key characteristic of many active galactic nuclei (AGN) is their variability, but its origin is poorly understood, especially in the radio domain. Williams et al. (2017) reported a ~50 per cent increase in peak flux ...

Radio continuum (RC) emission in galaxies allows us to measure star formation rates (SFRs) unaffected by extinction due to dust, of which the low-frequency part is uncontaminated from thermal (free-free) emission. We ...

Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR

Heesen, V.; Rafferty, D. A.; Horneffer, A.; Beck, R.; Basu, A.; Westcott, J.; Hindson, L.; Brinks, E.; Chyży, K. T.; Scaife, A. M. M.; Brüggen, M.; Heald, George; Fletcher, A.; Horellou, C.; Tabatabaei, F. S.; Paladino, R.; Nikiel-Wroczyński, B.; Hoeft, M.; Dettmar, R. -J. (2018-05-11)

Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role; they can be best traced with low-frequency radio continuum observations, which are less affected by spectral ageing. ...

Abell 1367: a high fraction of late-type galaxies displaying HI morphological and kinematic perturbations

Scott, T. C.; Brinks, E.; Cortese, L.; Boselli, A.; Bravo-Alfaro, H. (2018-04-21)

To investigate the effects the cluster environment has on late-type galaxies (LTGs), we studied HI perturbation signatures for all Abell 1367 LTGs with HI detections. We used new Very Large Array HI observations combined ...
