1.65 µm (H-band) surface photometry of galaxies. III: observations of 558 galaxies with the TIRGO 1.5m telescope. Abstract. We present near-infrared H-band (1.65 µm) surface photometry of 558 galaxies in the Coma Super-cluster and in the Virgo cluster. This data set, obtained with the Arcetri NICMOS3 camera ARNICA mounted on the Gornergrat Infrared Telescope, is aimed at complementing , with observations of mostly early-type objects, our NIR survey of spiral galaxies in these regions, presented in previous papers of this series. Magnitudes at the optical radius, total magnitudes, isophotal radii and light concentration indices are derived. We confirm the existence of a positive correlation between the near-infrared concentration index and the galaxy H-band luminosity.

متن کاملEvaluation of New MOND Interpolating Function with Rotation Curves of Galaxies
The rotation curves of a sample of 46 low- and high-surface brightness galaxies are considered in the context of Milgrom's modi_ed dynamics (MOND) to test a new interpolating function proposed by Zhao et al. (2010) [1] and compare with the results of simple interpolating function. The predicted rotation curves are calculated from the total baryonic matter based on the B-band surface photometry,...

متن کامل1 . 65 μ m ( H - band ) surface photometry of galaxies . VIII : the near - IR κ - space at z = 0
We present the distribution of a statistical sample of nearby galaxies in the κ-space (κ1 ∝ log M , κ2 ∝ log Ie, κ3 ∝ log M/L). Our study is based on near-IR (Hband: λ = 1.65 μm) observations, for the first time comprising earlyand late-type systems. Our data confirm that the mean effective dynamical mass-to-light ratio M/L of the E+S0+S0a galaxies increases with increasing effective dynamical ...
متن کاملobservations of giant low surface brightness galaxies
We have used the Nançay Radio Telescope to obtain new global H i data for 16 giant low surface brightness (LSB) galaxies. Our targets have optical luminosities and disk scale lengths at the high end for spiral galaxies (L B ∼ 10 10 L ⊙ and h r ∼ >6 kpc for H 0 =75 km s −1 Mpc −1), but they have diffuse stellar disks, with mean disk surface brightnesses ∼ >1 magnitude fainter than normal giant s...
