What Can the Radial Surface Brightness Profiles of Galaxy Discs Tell Us About Their Evolution?
Deriving the azimuthally averaged radial surface brightness profile of a galaxy is a schematic way of presenting the light and then the mass structure of disc...
What can we learn from constraining Extreme-Emission Line Galaxies models with large samples of local analogs?
Extreme Emission Line Galaxies (EELGs) are characterized by their compact sizes and very high equivalent widths of certain optical emission lines (e.g. EW([OIII...
What Can We Learn on the Structure and the Dynamics of the Solar Core with g Modes?
The detection of the signature of dipole gravity modes has opened the path to study the solar inner radiative zone. Indeed, g modes should be the best probes to...
What Disc Brightness Profiles Can Tell us about Galaxy Evolution
Azimuthally averaged surface brightness profiles of disc galaxies provide a most useful practical classification scheme which gives insights into their...
What do Astrophysics and the World's Oldest Profession have in Common?
In the present paper I want to tell of my impressions about the world of research in astrophysics, which I know from close observation. I see with certain...
Detection of optical surface brightness structures with magnitudes fainter than 30 mag/arcsec2 has remained elusive in current photometric deep surveys. We are...
What do RR Lyrae tell us about the formation of the Milky Way and M31 haloes?
RR Lyrae variables are old (>10 Gyr) stars and, as such, they are useful probes of the earliest events of star formation in galaxies (Bernard et al. 2008...
