Grand-design spirals in the core of NGC 5248
(2001)
We report the detection of a bisymmetric nuclear spiral structure in the spiral galaxy NGC 5248.The two red spiral arms can be followed for about 3 arcsec, before they appear to end inside the radius of the circumnuclear ...
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 ...
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 ...
M100 and NGC 6951: Morphological Clues to Central Dynamics
(Astronomical Society of the Pacific, 1996)
High-resolution optical and NIR observations are used to constrain a dynamical model of the circumnuclear star forming (SF) region in the barred galaxy M100 (NGC 4321). Small leading arms observed in our K-band image of ...
