Neutral hydrogen represents the major observable baryonic constituent of galaxies that fuels the formation of stars through the transformation in molecular hydrogen. The emission of the hydrogen recombination line Halpha is the most direct tracer of the process that transforms gas (fuel) into stars. We continue to present Halpha3 (acronym for Halpha-alpha-alpha), an extensive Halpha+[NII] narrow-band imaging campaign of galaxies selected from the HI Arecibo Legacy Fast ALFA Survey (ALFALFA…

Hα3: an Hα imaging survey of HI selected galaxies from ALFALFA - VI. The role of bars in quenching star formation from z = 3 to the present epoch
A growing body of evidence indicates that the star formation rate per unit stellar mass (sSFR) decreases with increasing mass in normal main-sequence star-forming galaxies. Many processes have been
Hα imaging of the Herschel Reference Survey The star formation properties of a volume-limited, K-band-selected sample of nearby late-type galaxies ,
We present new Hα+[NII] imaging data of late-type galaxies in the Herschel Reference Survey aimed at studying the star formation properties of a K-band-selected, volume-limited sample of nearby
Ha Images of Ultra-Flat Edge-On Spiral Galaxies

Abstract —We present the Hα images of ultra-flat (UF) spiral galaxies seen practically edgeon. The galaxies have the angular diameter in the B band $$a > 1.9'$$ and the apparent axial ratio ( a / b
An Hα Imaging Survey of the Low Surface Brightness Galaxies Selected from the Spring Sky Region of the 40% ALFALFA H i Survey
We present the observed H$\alpha$ flux and derived star formation rates (SFRs) for a fall sample of low$-$surface$-$brightness galaxies (LSBGs). The sample is selected from the fall sky region of the
Near-identical star formation rate densities from Hα and FUVat redshift zero
For the first time both H alpha and far-ultraviolet (FUV) observations from an HI-selected sample are used to determine the dust-corrected star formation rate density (SFRD: (rho)over dot) in the
Observational evidence of a slow downfall of star formation efficiency in massive galaxies during the past 10 Gyr
In this paper we study the causes of the reported mass-dependence of the slope of SFR-M* relation, the so-called "Main Sequence" of star-forming galaxies, and discuss its implication on the physical
Bar-driven evolution and quenching of spiral galaxies in cosmological simulations
• Physics

We analyse the output of the hi-res cosmological “zoom-in” hydrodynamical simulation ErisBH to study self-consistently the formation of a strong stellar bar in a Milky Way-type galaxy and its effect
An H$\alpha$ Imaging Survey of the Low-surface-brightness Galaxies Selected from the Fall Sky Region of the 40$\%$ ALFALFA \ion{H}{1} Survey
We present the observed H$\alpha$ flux and derived star formation rates (SFRs) for a fall sample of low$-$surface$-$brightness galaxies (LSBGs). The sample is selected from the fall sky region of the
The build-up of pseudo-bulges in a hierarchical universe

We study the cosmological build-up of pseudo-bulges using the L-Galaxies semi-analytical model for galaxy formation with a new approach for following separately the assembly of classical bulges and
The Downfall of Massive Star-Forming Galaxies During the Last 10\,\mathrm{Gyr}
In this chapter I discuss in more detail one of the observation that was reported in Chap. 2 (Schreiber et al, A&A, 575:A74 2015). By measuring the correlation between the $$\mathrm{SFR}$$ and the
