A Subarcsecond Resolution Near infrared Study of Seyfert and “Normal” Galaxies. I. Imaging Data
(1999-12)
We present new high-resolution near-infrared observations in the J, H, and K bands, obtained to study the properties of Seyfert host galaxies. The data set consists of images in the three bands of practically the entire ...
Observations of Barred Galaxies
(Astronomical Society of the Pacific, 1999)
We review general observational properties of bars in galaxies, and relations between bars, their dynamics, and (circum)nuclear activity. We consider new measurements of bar fractions and of the distribution of bars with ...
A Multi-Wave length Survey of the ISM in NGC 628
(Astronomical Society of the Pacific, 1999)
Is atomic hydrogen a precursor to or byproduct of the star formation process? Recent evidence suggests that a large percentage of the atomic hydrogen in spiral galaxies could be due to photodissociation of molecular gas ...
Resolving circumnuclear star formation in M100 with image stabilisation at UKIRT
(European Southern Observatory, 1999)
High-resolution UKIRT observations of circumnuclear star formation in M100
(1999-01)
We present high-resolution, near-infrared imaging of the circumnuclear region of the barred spiral galaxy M100 (=NGC 4321), accompanied by near-infrared spec- troscopy.We identify a total of 43 distinct regions in the ...
A nuclear grand-design spiral within the normal disc spiral of NGC 5248
(1999-01)
We report the discovery of trailing grand-design nuclear spiral structure in the spiral galaxy NGC 5248. Two tightly-wound red spiral arms, with widths less than 1 arcsec (~ 75 pc), emanate at 1 arcsec outside the quiescent ...
Circumnuclear Star-forming Regions in barred Galaxies
(1999)
We present high-resolution Hα velocity fields and rotation curves of the circum nuclear star-forming regions of five barred galaxies. Two of the five objects show substantially smaller initial rises than the three others; ...
