extracted from the SDSS-DR17 MaNGA survey, consists of 946 ETGs in clusters (cETGs) and 288 isolated ETGs (iETGs) within a spectroscopic redshiftz≤0.15. We investigated the distribution of these galaxies in the Fundamental Plane (

Dr. Sarah Jane Schmidt Dr. Schmidt studies the lowest mass and most numerous types of stars in our Galaxy – the M and L dwarfs. These types of cool stars have strong magnetic fields on their surfaces which results in special kinds of extra light from the stars, including dramatic flare ...

The SDSS project is an initiative aimed at mapping the universe. As the last data release of the fourth phase of SDSS, SDSS DR171, provides observational data covering more than one-third of the celestial sphere [3]. The stellar classification dataset we utilized is based on the stellar ...
