A dust lane in the radio galaxy 3C 270

, 1996
We present broadband surface photometry of the radio galaxy 3C 270 (NGC 4261). We find a distinct dust lane in the V-R image of the galaxy and determine its orientation and size.

Analysis of a Type II Supernova Candidate at z = 3.19 from JWST’s COSMOS-Web Survey

The Astrophysical Journal
The launch of the James Webb Space Telescope (JWST) has enabled the discovery of a small but increasing sample of high-redshift core-collapse supernovae (CC SNe), which provide new tests of massive star evolution in the early Universe.

Surface photometry of Virgo cluster galaxies - Barred galaxies

The Astronomical Journal, 1976
Photographic surface photometry in B and V is presented for three barred galaxies in the Virgo cluster: N4548, N4596, and N4608. Intercomparisons of luminosity and color profiles and standard photometric parameters indicate that for these galaxies: (1) the nuclear component follows the fourth-root-of-radius luminosity law for both B and V, (2) the ...

CCD surface photometry of galaxies [PDF]

, 1992
We present here the results based on analysis of broad band optical images of radio loud and radio quiet galaxies selected from a set of x-ray galaxies. Data reduction techniques, and surface photometry using the IRAF data reduction package are described.
