Dual-component stellar assembly histories in local elliptical galaxies via MUSE
Keerthana Jegatheesan, Evelyn J. Johnston, Boris Häußler +3
Elliptical galaxies often exhibit complex assembly histories, and are presumed to typically form through a combination of rapid, early star formation and subsequent accretion of ma…
BUDDI-MaNGA III: The mass-assembly histories of bulges and discs of spiral galaxies
Keerthana Jegatheesan, Evelyn J. Johnston, Boris Häußler +1
The many unique properties of galaxies are shaped by physical processes that affect different components of the galaxy - like the bulges and discs - in different ways, and leave ch…
BUDDI-MaNGA II: The Star-Formation Histories of Bulges and Discs of S0s
Evelyn J. Johnston, Boris Häußler, Keerthana Jegatheesan +7
Many processes have been proposed to explain the quenching of star formation in spiral galaxies and their transformation into S0s. These processes affect the bulge and disc in diff…
BUDDI-MaNGA I: A statistical sample of cleanly decomposed bulge and disc spectra
Evelyn J. Johnston, Boris Häußler, Keerthana Jegatheesan
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. T…
COSMOS2020: Manifold Learning to Estimate Physical Parameters in Large Galaxy Surveys
I. Davidzon, K. Jegatheesan, O. Ilbert +16
We present a novel method to estimate galaxy physical properties from spectral energy distributions (SEDs), alternate to template fitting techniques and based on self-organizing ma…
