SN Ia host galaxy properties from Sloan Digital Sky Survey-II spectroscopy
(Oxford University Press, 2013)
We study the stellar populations of Type Ia supernova (SN Ia) host galaxies using Sloan Digital Sky Survey (SDSS)-II spectroscopy. The main focus is on the relationships of SN Ia properties with stellar velocity dispersion ...
Synergies between intensity maps of hydrogen lines
(Oxford University Press, 2018)
We study synergies between Hi 21cm and Hα intensity map observations, focusing on SKA1- like and SPHEREx-like surveys. We forecast how well such a combination can measure features in the angular power spectrum on the ...
HerMES: Candidate gravitationally lensed galaxies and lensing statistics at submillimeter wavelengths
(American Astronomical Society, 2013)
Gravitational lensing increases the angular size and integrated flux of affected sources. It is exploited to investigate the mass distribution of the foreground lensing structures and the properties of the background lensed ...
