Does a merging event always precede AGN activity? In this starting PhD project, we will try to address this question by quantifying the distortions and interaction signatures that can be detected on a sample of AGN galaxies from the ACS-COSMOS survey. In order to do this, we will investigate and combine all the different available galaxy

Towards ensemble asteroseismology of the young open clusters χ Persei and NGC 6910
As a result of the variability survey in χ Persei and NGC 6910, the number of β Cep stars that are members of these two open clusters is increased to twenty stars, nine in NGC 6910 and eleven in χ Persei. We compare pulsational properties, in particular the frequency spectra, of β Cep stars in both clusters and explain the differences in terms of

Towards the next frontier in high precision solar polarimetry: 10^-4
In the last two decades, solar physics has greatly explored the 10^-3 polarimetric sensitivity level (referred to the continuum intensity). This has provided us with a quantitatively accurate picture of the photospheric magnetism for mean longitudinal fields in the range of about 5 Gauss. However, the same 10^-3 detection levels translate into a

Tracking the impact of environment on the galaxy stellar mass function up to z ~ 1 in the 10 k zCOSMOS sample
We study the impact of the environment on the evolution of galaxies in the zCOSMOS 10 k sample in the redshift range 0.1 ≤ z ≤ 1.0 over an area of ~1.5 deg2. The considered sample of secure spectroscopic redshifts contains about 8500 galaxies, with their stellar masses estimated by SED fitting of the multiwavelength optical to near-infrared (NIR)

Transit timing analysis of the exoplanets TrES-1 and TrES-2
Aims. The aim of this work is a detailed analysis of transit light curves from TrES-1 and TrES-2, obtained over a period of three to four years, in order to search for variabilities in observed mid-transit times and to set constraints on the presence of additional third bodies. Methods: Using the IAC 80 cm telescope, we observed transits of TrES-1

Transit timing variation and transmission spectroscopy analyses of the hot Neptune GJ3470b
GJ3470b is a hot Neptune exoplanet orbiting an M dwarf and the first sub-Jovian planet to exhibit Rayleigh scattering. We present transit timing variation (TTV) and transmission spectroscopy analyses of multiwavelength optical photometry from 2.4-m and 0.5-m telescopes at the Thai National Observatory, and the 0.6-m PROMPT-8 telescope in Chile. Our
