Star formation and stellar populations across nuclear rings in galaxies
M. Sarzi, E. L. Allard, J. H. Knapen +1
(Abridged) We present a study of the optical spectra of a sample of eight star-forming nuclear rings and the nuclei of their host galaxies. The spectra were obtained with the ISIS…
Star formation in the central regions of galaxies
J. H. Knapen, E. L. Allard, L. M. Mazzuca +2
Massive star formation in the central regions of spiral galaxies plays an important role in the dynamical and secular evolution of their hosts. Here, we summarise a number of recen…
Stars and Gas in the Inner Parts of Galaxies seen in SAURON Integral Field Observations
R. F. Peletier, K. Fathi, E. L. Allard +7
We give two examples of spiral galaxies that show non-circular gas motions in the inner kiloparsecs, from SAURON integral field spectroscopy. We use harmonic decomposition of the v…
The Star Formation History and Evolution of the Circumnuclear Region of M100
Emma L. Allard, Johan H. Knapen, Reynier F. Peletier +1
(Abridged) Star-forming nuclear rings in barred galaxies are common in nearby spirals, and their detailed study can lead to important insights into the evolution of galaxies, their…
Pseudobulges in the Disk Galaxies NGC 7690 and NGC 4593
John Kormendy, Mark E. Cornell, David L. Block +2
We present Ks-band surface photometry of NGC 7690 (Hubble type Sab) and NGC 4593 (SBb). We find that, in both galaxies, a major part of the "bulge" is as flat as the disk and has a…
Cool Gas and Massive Stars - the Nuclear Ring in M100
Emma L. Allard, Reynier F. Peletier, Johan H. Knapen
The SAURON integral field spectrograph was used to observe the central area of the barred spiral galaxy M100 (NGC 4321). M100 contains a nuclear ring of star formation, fueled by g…
