AGC198606: A gas-bearing dark matter minihalo?
E. A. K. Adams, Y. Faerman, W. F. Janesh +9
We present neutral hydrogen (HI) imaging observations with the Westerbork Synthesis Radio Telescope of AGC198606, an HI cloud discovered in the ALFALFA 21cm survey. This object is…
The HI absorption "Zoo"
K. Gereb, F. M. Maccagni, R. Morganti +1
We present an analysis of the HI absorption in a sample of 101 flux-selected radio AGN (S_1.4 GHz > 50 mJy) observed with the Westerbork Synthesis Radio Telescope (WSRT). HI absorp…
The jet-ISM interaction in the Outer Filament of Centaurus A
F. Santoro, J. B. R. Oonk, R. Morganti +1
The interaction between the radio plasma ejected by the active nucleus of a galaxy and the surrounding medium is a key process that can have a strong impact on the interstellar med…
The Atlas3D project -- XXIX. The new look of early-type galaxies and surrounding fields disclosed by extremely deep optical images
Pierre-Alain Duc, Jean-Charles Cuillandre, Emin Karabal +24
Galactic archeology based on star counts is instrumental to reconstruct the past mass assembly of Local Group galaxies. The development of new observing techniques and data-reducti…
The WSRT HALOGAS Survey
George Heald, the HALOGAS Team
We present an overview of the HALOGAS (Hydrogen Accretion in LOcal GAlaxieS) Survey, which is the deepest systematic investigation of cold gas accretion in nearby spiral galaxies t…
The extended structure of the dwarf irregular galaxy Sagittarius
G. Beccari, M. Bellazzini, F. Fraternali +6
We present a detailed study of the stellar and HI structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the surface brightness pro…
What triggers a radio AGN? The intriguing case of PKSB 1718-649
F. M. Maccagni, R. Morganti, T. A. Oosterloo +1
We present new Australia Telescope Compact Array (ATCA) observations of the young (< 10^2 years) radio galaxy PKS B1718-649. We study the morphology and the kinematics of the neutr…
Connection between dynamically derived IMF normalisation and stellar population parameters
Richard M. McDermid, Michele Cappellari, Katherine Alatalo +22
We report on empirical trends between the dynamically determined stellar initial mass function (IMF) and stellar population properties for a complete, volume-limited sample of 260…
The Atlas3D project - XXIV. The intrinsic shape distribution of early-type galaxies
Anne-Marie Weijmans, P. T. de Zeeuw, Eric Emsellem +23
We use the Atlas3D sample to perform a study of the intrinsic shapes of early-type galaxies, taking advantage of the available combined photometric and kinematic data. Based on our…
A low HI column density filament in NGC 2403: signature of interaction or accretion
W. J. G. de Blok, Katie M. Keating, D. J. Pisano +6
Observed HI accretion around nearby galaxies can only account for a fraction of the gas supply needed to sustain the currently observed star formation rates. It is possible that ad…
Probing the gas content of radio galaxies through HI absorption stacking
K. Gereb, R. Morganti, T. Oosterloo
Using the WSRT, we carried out shallow HI absorption observations of a flux-selected (S > 50 mJy) sample of 93 radio AGN with available SDSS redshifts between 0.02 < z < 0.23. We s…
Jet acceleration of the fast molecular outflows in the Seyfert galaxy IC5063
C. Tadhunter, R. Morganti, M. Rose +2
Massive outflows driven by active galactic nuclei (AGN) are widely recognised to play a key role in the evolution of galaxies, heating the ambient gas, expelling it from the nuclea…
The extended structure of the dwarf irregular galaxies Sextans A and Sextans B. Signatures of tidal distortion in the outskirts of the Local Group
M. Bellazzini, G. Beccari, F. Fraternali +7
We present a detailed study of the stellar and HI structure of the dwarf irregular galaxies SextansA and SextansB, members of the NGC3109 association. We use newly obtained deep (r…
The ATLAS3D Project - XXVIII. Dynamically-driven star formation suppression in early-type galaxies
Timothy A. Davis, Lisa M. Young, Alison F. Crocker +22
We present measurements of the star formation rate (SFR) in the early-type galaxies (ETGs) of the ATLAS3D sample, based on Wide-field Infrared Survey Explorer (WISE) 22um and Galax…
The Atlas3D project - XXVI. HI discs in real and simulated fast and slow rotators
Paolo Serra, Ludwig Oser, Davor Krajnovic +24
One quarter of all nearby early-type galaxies (ETGs) outside Virgo host a disc/ring of HI with size from a few to tens of kpc and mass up to ~1e+9 solar masses. Here we investigate…
