Galaxy Photometry in the Cluster Shakhbazian I
Newly obtained photoelectric V magnitudes for three galaxies in Shakhbazian I, when combined with the virial analysis of Robinson and Wampler, show that the cluster mass-to-luminosity ratio is WL ~ 4. The first brightest galaxy in the cluster (an elliptical) has (U—B) and (B—V) color indices which are consistent with those of normal ellipticals in the Virgo and Coma clusters, and it is suggeste...
متن کاملDeep surface photometry of edge - on spirals in Abell galaxy clusters : constraining environmental effects
Context. There is a clear scarcity of structural parameters for stellar thick discs, especially for spiral galaxies located in high-density regions, such as galaxy clusters and compact groups. Aims. We have modelled the thin and thick discs of 4 edge-on spirals located in Abell clusters: NGC 705, ESO243G49, ESO187G19, LCSBS0496P. Deep I band images of NGC 705 were taken from the HST archive, wh...
متن کاملWide Field CCD Surface Photometry of the Giant Elliptical Galaxy NGC 4472 in the Virgo Cluster
We present deep wide field (16.4× 16.4 ) Washington CT1 CCD surface photometry of the giant elliptical galaxy NGC 4472, the brightest member in the Virgo cluster. Our data cover a wider field than any previous CCD photometry as well as going deeper. Surface brightness profiles of NGC 4472 are not well fit by a single King model, but they can be fit approximately by two King models: with separat...
متن کاملThe Iras Bright Galaxy Sample. v. Multibeam Photometry of Galaxies
Forty-seven galaxies from the IRAS Bright Galaxy Sample with infrared luminosities Lm > 10 1 Lq have been measured at 1.3, 1.65, and 2.2 ¡im with beam diameters of 17", 33", and 55". These measurements, combined with 5" and 10" observations presented in an earlier paper, provide an opportunity to study the spatial distribution of the near-infrared emission in luminous IRAS galaxies. It is found...
متن کاملSpiral galaxy distance indicators based on near-infrared photometry
We compare two methods of distance determination to spiral galaxies using optical/near-infrared (NIR) observations, the (I–K) versus MK colour – absolute magnitude (CM) relation and the I and K-band Tully-Fisher relation (TFR). Dust-free colours and NIR absolute magnitudes greatly enhance the usefulness of the NIR CM relation as a distance indicator for moderately to highly inclined spiral gala...
