Abstract:
We present new 2D high resolution Fabry-Perot spectroscopic
observations of 152 star-forming galaxies which are part of the
Herschel Reference Survey (HRS), a complete K-band selected,
volume-limited sample of nearby galaxies, spanning a wide range in
stellar mass and morphological type.
Using improved data reduction techniques that provide adaptive binning
based on Voronoi tessellation, using large field-of-view observations,
we derive high spectral resolution (R>10,000) Hα datacubes from
which we compute Hα maps and radial 2D velocity fields that are
based on several thousand independent measurements. A robust method
based on such fields allows us to accurately compute rotation curves
and kinematical parameters, for which uncertainties are calculated
using a method based on the power spectrum of the residual velocity
fields.
We check the consistency of the rotation curves by comparing our
maximum rotational velocities to those derived from Hi data, and
computing the i-band, NIR, stellar and baryonic Tully-Fisher
relations. We use this set of kinematical data combined to those
available at other frequencies to study for the first time the
relation between the dynamical and the total baryonic mass (stars,
atomic and molecular gas, metals and dust), and derive the baryonic
and dynamical main sequence on a representative sample of the local
universe.
Description:
The Herschel Reference Survey (HRS) is a K-band-selected
volume-limited (15<D<25Mpc) complete sample of 323 galaxies
spanning a wide range in morphological type (from ellipticals to
late-type spirals and irregulars) and stellar mass
(108<M*<1011M☉).
In this work we present new Fabry-Perot data for 152 HRS star forming
galaxies observed at the OHP.
Fabry-Perot observations scanning the Hα emission line of 152
late-type galaxies have been obtained along 91 nights at the OHP (9
runs from February 2016 to April 2018).
