Satellite galaxies in nearby groups of galaxies

, 2015
We analyse distribution, kinematics and star-formation (SF) properties of satellite galaxies in three different samples of nearby groups. We find that studied groups are generally well approximated by low-concentration NFW model, show a variety of LOS velocity dispersion profiles and signs of SF quenching in outskirts of dwarf satellite galaxies.

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Introducing the Condor Array Telescope. V. Deep Broad- and Narrowband Imaging Observations of the M81 Group

The Astrophysical Journal Supplement Series
We used the Condor Array Telescope to obtain deep imaging observations through the luminance broadband and He ii 468.6 nm, [O iii ] 500.7 nm, He i 587.5 nm, H α , [N ii ] 658.4 nm, and [S ii ] 671.6 nm narrowband filters of an extended region comprising ...

The Padova-Millennium Galaxy and Group Catalogue (PM2GC): the group-finding method and the PM2GC catalogues of group, binary and single field galaxies

, 2011
We present the construction and describe the properties of the Padova-Millennium Galaxy and Group Catalogue (PM2GC), a galaxy catalogue representative of the general field population in the local Universe.

The effect of simulated intergroup encounters on movement patterns and home range use in banded mongooses

Wildlife Biology, EarlyView.
Intergroup conflicts have a wide range of impacts, including affecting movement and ranging patterns. Previous studies found contrasting movement responses to intergroup conflicts, but no explanation for these differences has been suggested. However, these can be broadly grouped into ‘conflict avoidance' responses: avoiding areas close to the fight ...

Introducing the Condor Array Telescope. VI. Discovery of Extensive Ionized Gaseous Filaments of the Cosmic Web in the Direction of the M81 Group

The Astrophysical Journal
We used the Condor Array Telescope to obtain deep imaging observations through luminance broadband and He ii , [O iii ], He i , H α , [N ii ], and [S ii ] narrowband filters of an extended region of the M81 Group spanning ≈8 × 8 deg ^2 on the sky ...

The origin of redshift asymmetries: How LambdaCDM explains anomalous redshift

, 2008
Several authors have found a statistically significant excess of galaxies with higher redshifts relative to the group centre, so-called discordant redshifts, in particular in groups where the brightest galaxy, identified in apparent magnitudes, is a ...

‘A Sort of Armed Argument’: Ireland's Civil War of Words

History, EarlyView.
Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.

A Deep Dive into the NGC 741 Galaxy Group: Insights into a Spectacular Head-tail Radio Galaxy from VLA, MeerKAT, uGMRT, and LOFAR

The Astrophysical Journal
We present deep, wideband multifrequency radio observations (144 MHz−8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the infalling head-tail radio galaxy (NGC 742) and the main group.
