چکیده

We examine the H I content of spiral galaxies in groups by using a catalog of loose groups of galaxies identified in a magnitude limited sample (mZ ≤ 15.7) spanning the range 8 ≤ α ≤ 18 in right ascension and +9 ≤ δ ≤ +15 in declination. The redshift completeness of the galaxy sample is ∼ 95%. No significant effect of H I depletion is found, although there may be a hint that the earliest type spirals are slightly deficient. Subject headings: Galaxies: H I content – galaxies: loose-groups

Evaluation 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,...

Stellar Populations in the Central Galaxies of Fossil Groups

It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...

Pulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I

We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

Southern GEMS groups II : HI distribution , mass functions and HI deficient galaxies ⋆

We investigate the neutral hydrogen (H i) content of sixteen groups for which we have multi-wavelength data including X-ray observations. Wide-field imaging of the groups was obtained with the 20-cm multibeam system on the 64-m Parkes telescope. We have detected ten previously uncatalogued H i sources, one of which has no visible optical counterpart. We examine the H i properties of the groups,...

Cultural Content Analysis of Iranian ELT Coursebooks: A Comparison of Vision I & II with English for Pre-University students I & II

This study was conducted to evaluate the cultural contents and cultural elements represented in Vision (I & II) and Pre-University English (I & II). This study also aimed at determining if there were significant differences between these series in terms of cultural content and cultural element representation. To this end, the two ELT coursebook series were selected and analyzed based on Cortazz...
