Constraining dark energy using real and mock galaxy surveys [PDF]
, 2009 In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

EPJ Web of Conferences, 2017 We present results of the Araucaria Project’s investigation of RR Lyrae stars as distance indicators in nearby galaxies. With an aid of near-infrared period-luminositymetallicity relations available in the literature we determined distance moduli to five

Mid-infrared spectroscopy of candidate active galactic nuclei-dominated submillimeter galaxies [PDF]
, 2010 Spitzer spectroscopy has revealed that ≃80% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining ≃20% that show signs of harboring powerful active galactic nuclei (AGNs).

The First Exploration of the Correlations Between WISE 12 μm and CO Emission in Early-type Galaxies
The Astrophysical JournalWe present the analysis of a comprehensive sample of 352 early-type galaxies using public data, to investigate the correlations between CO luminosities and mid-infrared luminosities observed by Wide-field Infrared Survey Explorer.

The Search for Very High Energy γ-rays from Misaligned AGN [PDF]
, 2013 The aim of this work is to study the potential for emission at very high energies (100 GeV) by misaligned active galactic nuclei (AGN) and the future prospects for observations of these objects with the next generation imaging atmospheric Cherenkov ...

GRB Host Galaxies: An Unbiased Sample [PDF]
, 2011 We describe the current status and recent results from our Swift/VLT legacy survey, a VLT Large Programme aimed at characterizing the host galaxies of a homogeneously selected sub-sample of Swift GRBs.

Star clusters in unperturbed spiral galaxies [PDF]
, 2008 Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

The star formation history of early-type galaxies in the fornax cluster [PDF]
, 1998 We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.
