Searching in HI for Massive Low Surface Brightness Galaxies: II. Completing the UGC Sample

Karen O'Neil, Wim van Driel, Stephan Schneider

Although Low Surface Brightness (LSB) galaxies are increasingly well studied, considerable uncertainty still exists as to both their range in properties and their evolutionary hist…

The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster

Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51

The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…

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…

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…

The WSRT ZoA Perseus-Pisces Filament wide-field HI imaging survey I. HI catalogue and atlas

M. Ramatsoku, M. A. W Verheijen, R. C. Kraan-Korteweg +7

We present results of a blind 21cm HI-line imaging survey of a galaxy overdensity located behind the Milky Way at 160 deg, 0.5 deg. The overdensity corresponds t…

Can galaxy growth be sustained through HI-rich minor mergers?

M. D. Lehnert, W. van Driel, R. Minchin

Local galaxies with specific star-formation rates (star-formation rate per unit mass; sSFR~0.2-10/Gyr) as high as distant galaxies (z~1-3), are very rich in HI. Those with low stel…

Subarcsecond international LOFAR radio images of the M82 nucleus at 118 MHz and 154 MHz

E. Varenius, J. E. Conway, I. Martí-Vidal +25

The nuclear starburst in the nearby galaxy M82 provides an excellent laboratory for understanding the physics of star formation. This galaxy has been extensively observed in the pa…

Discovery of Carbon Radio Recombination Lines in M82

Leah K. Morabito, J. B. R. Oonk, Francisco Salgado +30

Carbon radio recombination lines (RRLs) at low frequencies (<=500 MHz) trace the cold, diffuse phase of the interstellar medium, which is otherwise difficult to observe. We present…

M87 at metre wavelengths: the LOFAR picture

F. de Gasperin, E. Orru', M. Murgia +92

M87 is a giant elliptical galaxy located in the centre of the Virgo cluster, which harbours a supermassive black hole of mass 6.4x10^9 M_sun, whose activity is responsible for the…

Characteristics of thick disks formed through minor mergers: stellar excesses and scale lengths

Yan Qu, Paola Di Matteo, Matthew D. Lehnert +1

By means of N-body/SPH simulations we investigate the morphological properties of thick disks formed through minor mergers. We show that the vertical surface density profile of the…

The slowing down of galaxy disks in dissipationless minor mergers

Yan Qu, Paola Di Matteo, Matthew Lehnert +2

We have investigated the impact of dissipationless minor galaxy mergers on the angular momentum of the remnant. Our simulations cover a range of initial orbital characteristics and…
