Website: sdss.org/dr15/future/lvm/ The Local Volume Mapper (LVM) is an optical, integral-field spectroscopic survey that will target the Milky Way, Small and Large Magellanic Clouds, M31, and other Local Volume galaxies. LVM will make use of newly built spectrographs that cover a wavelength range of 3600-10000 Å, with spectral resolution R~4000. It will collect more than […]

Website: nucleomilenioeris.cl One of the first diagrammatic evolutionary “trees” was created by Charles Darwin in his book “On the Origin of Species”, and since then phylogenetic trees have been used in biological sciences to represent evolutionary relationships among organisms. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from
Many galaxies display clear bulges and discs, and understanding how these components form is a vital step towards understanding how the galaxy has evolved into what we see today. The BUDDI-MaNGA project aims to study galaxy evolution and morphological transformations through the star-formation histories of the bulges and discs. We have applied our BUDDI software
BUDDI (Bulge-Disc Decomposition of IFU data cubes) is a new approach to fit the two-dimensional light profiles of galaxies as a function of wavelength to extract the spectral properties of these galaxies’ discs and bulges. Our approach is to model the 2-dimensional light profile of the galaxy in every image slice of the datacube, creating
