Scalar perturbations in gravity using the covariant approach

Shambel Sahlu, Joseph Ntahompagaze, Amare Abebe +2

The cosmological scalar perturbations of standard matter are investigated in the context of extended teleparallel gravity theories using the covariant formalism. After…

The Chaplygin gas as a model for modified teleparallel gravity?

Shambel Sahlu, Joseph Ntahompagaze, Maye Elmardi +1

This paper explores the possibility of treating the exotic Chaplygin-gas (CG) fluid model as some manifestation of an gravitation. To this end, we use the different cosmolog…

The Structure of a Quasi-Keplerian Accretion Disk around Magnetized Stars

Isaac Habumugisha, Edward Jurua, Solomon B. Tessema +1

In this paper, we present the complete structure of a quasi-Keplerian thin accretion disk with an internal dynamo around a magnetized neutron star. We assume a full quasi-Keplerian…

A morphological study of galaxies in ZwCl0024+1652, a galaxy cluster at redshift z 0.4

Zeleke Beyoro Amado, Mirjana Pović, Miguel Sánchez-Portal +9

The well-known cluster of galaxies ZwCl0024+1652 at z 0.4, lacks an in-depth morphological classification of its central region. While previous studies provide a visual clas…

Star formation in far-IR AGN and non-AGN galaxies in the green valley. II. Morphological analysis

Antoine Mahoro, Mirjana Pović, Pheneas Nkundabakura +2

This paper studies morphological properties of 103 green valley FIR active and 2609 non-active galaxies presented in Mahoro et al. 2017. The photometric data from the COSMOS survey…
