Gas-to-Dust mass ratios in local galaxies over a 2 dex metallicity range

A. Rémy-Ruyer, S. C. Madden, F. Galliano +17

This paper analyses the behaviour of the gas-to-dust mass ratio (G/D) of local Universe galaxies over a large metallicity range. We combine three samples: the Dwarf Galaxy Survey,…

Herschel SPIRE-FTS Observations of Excited CO and [CI] in the Antennae (NGC 4038/39): Warm and Cold Molecular Gas

Maximilien R. P. Schirm, Christine D. Wilson, Tara J. Parkin +14

We present Herschel SPIRE-FTS observations of the Antennae (NGC 4038/39), a well studied, nearby ( Mpc) ongoing merger between two gas rich spiral galaxies. We detect 5 CO tran…

Structure and Kinematics of the Nearby Dwarf Galaxy UGCA 105

Philip Schmidt, Gyula Jozsa, Gianfranco Gentile +5

Owing to their shallow stellar potential, dwarf galaxies possess thick gas disks, which makes them good candidates for studies of the galactic vertical kinematical structure. We pr…

G2C2 II: Integrated colour-metallicity relations for Galactic Globular Clusters in SDSS passbands

Joachim Vanderbeke, Michael J. West, Roberto De Propris +8

We use our integrated SDSS photometry for 96 globular clusters in and , as well as and photometry for a subset of 56 clusters, to derive the integrated colour-metall…

HALOGAS observations of NGC 5023 and UGC 2082: Modeling of non-cylindrically symmetric gas distributions in edge-on galaxies

P. Kamphuis, R. J. Rand, G. I. G. Józsa +7

In recent years it has become clear that the vertical structure of disk galaxies is a key ingredient for understanding galaxy evolution. In particular, the presence and structure o…

An Overview of the Dwarf Galaxy Survey

S. C. Madden, A. Remy Ruyer, M. Galametz +38

The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of…

The Herschel Exploitation of Local Galaxy Andromeda (HELGA). VI. The distribution and properties of molecular cloud associations in M31

Jason M. Kirk, Walter K. Gear, Jacopo Fritz +18

In this paper we present a catalogue of Giant Molecular Clouds (GMCs) in the Andromeda (M31) galaxy extracted from the Hershel Exploitation of Local Galaxy Andromeda (HELGA) datase…

Polar ring galaxies as tests of gravity

F. Lüghausen, B. Famaey, P. Kroupa +5

Polar ring galaxies are ideal objects with which to study the three-dimensional shapes of galactic gravitational potentials since two rotation curves can be measured in two perpend…

Herschel/SPIRE Sub-millimeter Spectra of Local Active Galaxies

Miguel Pereira-Santaella, Luigi Spinoglio, Gemma Busquet +11

We present the sub-millimeter spectra from 450 GHz to 1550 GHz of eleven nearby active galaxies observed with the SPIRE Fourier Transform Spectrometer (SPIRE/FTS) onboard Herschel.…
