Exploring the physics of ram pressure stripping with radio continuum observations in the SKA era
Alessandro Ignesti, Ian D. Roberts, Henrik W. Edler +4
Satellite galaxies in clusters are significantly more likely to be red and passive than similar mass galaxies in the field. This fact is known as the environmental quenching of gal…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
The longest known tails of ram-pressure-stripped star-forming galaxies are caused by an intracluster medium shock in Abell 1367
H. W. Edler, M. Hoeft, S. Bhagat +10
The environment plays an important role in shaping the evolution of cluster galaxies through mechanisms such as ram pressure stripping (RPS), whose effect may be enhanced in mergin…
The Competing Influence of Ram Pressure and Tidal Interaction in NGC 2276
Luka Matijević, Neven Tomičić, Antonino Marasco +9
The evolution of galaxies in groups is profoundly influenced by a variety of physical processes, with ram pressure and tidal interactions playing pivotal roles in shaping their str…
JWST Reveals a Candidate Jellyfish Galaxy at z=1.156
Ian D. Roberts, Michael L. Balogh, Visal Sok +3
We report the discovery of COSMOS2020-635829 as a candidate jellyfish galaxy undergoing ram pressure stripping in a (proto)cluster at . High-resolution imaging from the Jame…
Euclid: Early Release Observations of ram-pressure stripping in the Perseus cluster. Detection of parsec scale star formation with in the low surface brightness stripped tails of UGC 2665 and MCG +07-07-070
Koshy George, A. Boselli, J. -C. Cuillandre +177
Euclid is delivering optical and near-infrared imaging data over 14,000 deg on the sky at spatial resolution and surface brightness levels that can be used to understand the mo…
Deep galaxy stellar mass functions as a function of star formation rate in the Virgo cluster environment
Cameron R. Morgan, Elizaveta Sazonova, Ian D. Roberts +8
We analyze deep () galaxy stellar mass functions (SMFs) of the Virgo cluster using stellar masses derived as part of the Next Generation Virgo Survey (N…
Truncated star formation and ram pressure stripping in the Coma Cluster
Ariel O. Broderick, Ian D. Roberts, Michael J. Hudson
We use 45 galaxies from the Mapping Nearby Galaxies at Apache Point Observatory survey to study the physical drivers of star formation quenching in the Coma cluster. We measure spe…
No Evidence of Asymmetrically Enhanced Star Formation in Infalling Galaxies in UNIONS
Lauren M. Foster, Laura C. Parker, Stephen Gwyn +5
Ram pressure stripping is a well-known environmental quenching mechanism that removes gas from galaxies infalling into groups and clusters. In some extreme examples of ram pressure…
The Merging Galaxy Cluster Environment Affects the Morphology of Radio-AGN
Mary Rickel, Emily Moravec, Yjan A. Gordon +4
It has previously been found that the galaxy cluster environment can affect the fueling and evolution of Active Galactic Nuclei (AGN). This work examines the effect of the merging…
Merger Shocks Enhance Quenching in Local Galaxy Clusters
Ian D. Roberts
We report evidence for enhanced quenching in low-redshift galaxy clusters hosting radio relics. This effect is strongest for low-mass galaxies and is consistent with a rapid quench…
A 100 kpc Ram Pressure Tail Trailing the Group Galaxy NGC 2276
I. D. Roberts, R. J. van Weeren, F. de Gasperin +5
We present the discovery of a 100 kpc low-frequency radio tail behind the nearby group galaxy, NGC 2276. The extent of this tail is a factor of ten larger than previously reported…
ViCTORIA project: The LOFAR-view of environmental effects in Virgo Cluster star-forming galaxies
H. W. Edler, I. D. Roberts, A. Boselli +5
Environmental effects such as ram-pressure stripping (RPS) shape the evolution of galaxies in dense regions. We use the nearby Virgo cluster as a laboratory to study environmental…
Radio-continuum spectra of ram pressure stripped galaxies in the Coma Cluster
I. D. Roberts, R. J. van Weeren, D. V. Lal +7
We used the nearby Coma Cluster as a laboratory in order to probe the impact of ram pressure on star formation as well as to constrain the characteristic timescales and vel…
VERTICO and IllustrisTNG: The spatially resolved effects of environment on galactic gas
Adam R. H. Stevens, Toby Brown, Benedikt Diemer +15
It has been shown in previous publications that the TNG100 simulation quantitatively reproduces the observed reduction in each of the total atomic and total molecular hydrogen gas…
On the encounter between the GASP galaxy JO36 and the radio plume of GIN 049
Alessandro Ignesti, Marisa Brienza, Benedetta Vulcani +15
We report on the serendipitous discovery of an unprecedented interaction between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was made thanks to LOFAR observ…
