Untangling galaxy components: full spectral bulge-disc decomposition
Martha Tabor, Michael Merrifield, Alfonso Aragón-Salamanca +3
To ascertain whether photometric decompositions of galaxies into bulges and disks are astrophysically meaningful, we have developed a new technique to decompose spectral data cubes…
SDSS-IV MaNGA: Bulge-Disc Decomposition of IFU Datacubes (BUDDI)
Evelyn J. Johnston, Boris Haeussler, Alfonso Aragon-Salamanca +12
With the availability of large integral-field unit (IFU) spectral surveys of nearby galaxies, there is now the potential to extract spectral information from across the bulges and…
ASASSN-15oi: A Rapidly Evolving, Luminous Tidal Disruption Event at 216 Mpc
T. W. -S. Holoien, C. S. Kochanek, J. L. Prieto +17
We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the center of 2MASX J20390918-3045201 ($…
