Tracing the vertical composition of disc galaxies through colour gradients
Richard de Grijs, Reynier F. Peletier
(Abbreviated) Optical observations of a statistically complete sample of edge-on disc galaxies are used to study the intrinsic vertical colour gradients in the galactic discs, to c…
Supernova Remnants in the Fossil Starburst in M82
Richard de Grijs, Robert W. O'Connell, George D. Becker +2
We report the discovery of ten compact H-alpha-bright sources in the post-starburst region northeast of the center of M82, ``M82 B.'' These objects have H alpha luminosities and si…
Spiral galaxy distance indicators based on near-infrared photometry
R. de Grijs, R. F. Peletier
We compare two methods of distance determination to spiral galaxies using optical/near-infrared (NIR) observations, the (I-K) versus M_K colour - absolute magnitude (CM) relation a…
The Fossil Starburst in M82
Richard de Grijs, Robert W. O'Connell, John S. Gallagher
We present high-resolution optical and near-infrared HST observations of two adjacent regions in the fossil starburst region in M82, M82 B1 and B2. The presence of both the active…
