High proper motion objects towards the inner Milky Way: characterisation of newly identified nearby stars from the VISTA Variables in the Via Lactea Survey

M. Gromadzki, R. Kurtev, J. C. Beamin +10

The census of the Solar neighbourhood is still incomplete, as demonstrated by recent discoveries of many objects within 5-10 pc from the Sun. The area around the mid-plane and bulg…

Chaplygin-gas Solutions of f(R) Gravity

Maye Elmardi, Amare Abebe, Abiy Tekola

We explore exact f(R) gravity solutions that mimic Chaplygin-gas inspired LCDM cosmology. Starting with the original and modified Chaplygin gas equations of state, we reconstruct t…

Super Star Clusters in Luminous Infrared Galaxies: the SUNBIRD Survey

P. Vaisanen, Z. Randriamanakoto, A. Escala +7

We present recent results from an adaptive optics imaging survey of 40 Luminous IR Galaxies (LIRGs) searching for obscured core collapse supernovae and studying the galaxies themse…

The yellow hypergiant HR 5171 A: Resolving a massive interacting binary in the common envelope phase

O. Chesneau, A. Meilland, E. Chapellier +20

We initiated long-term optical interferometry monitoring of the diameters of unstable yellow hypergiants (YHG) with the goal of detecting both the long-term evolution of their radi…

What size halos do local LIRGs live in?

Abiy G. Tekola, Andreas A. Berlind, Petri Vaisanen

This work investigates the preferred environment of local Luminous IR Galaxies (LIRGs) in terms of the host halos that they inhabit, and in comparison to a control galaxy sample. T…

The Environments of Local Luminous Infrared Galaxies: Star Formation Rates increase with Density

Abiy G. Tekola, Petri Vaisanen, Andreas Berlind

This work studies the environments and star formation relationships of local luminous infrared galaxies (LIRG) in comparison to other types of local and distant (z~1) galaxies. The…

Spherically symmeteric dark energy structure in the context of Chaplygin gas model

Abiy G. Tekola

Spherically symmetric dark energy structures are investigated in the framework of a generalized Chaplygin gas (GCG), which has an equation of state of the form $P = - A/ρ^α} $. We…
