We present a novel method for measuring the Hubble rate from spectroscopic galaxy surveys effectively marginalising over the physical size of the sound horizon. We argue this measurement may be used as a consistency test of a given cosmological model.

We compute observables of the kinetic Sunyaev-Zeldovich (kSZ) effect in the presence of ultra-light axion dark matter. We show that next generation observations of the kSZ effect have the potential to constrain cosmic axion abundance.

We investigate the amplitude of matter density fluctuations unsing CMB lensing reconstruction from the Atacama Cosmology Telescope (ACT) and the unWISE galaxy survey.

We aim to transfer Planck’s absolute calibration based on the motional dipole induced by the satellite’s orbit around the solar system barycenter to ALMA. Because Planck and ALMA were not observing at the same time and many of the compact sources used for the comparison are variable we use ACT data to “bridge” the gap between them.

We apply the methodology developed in previous work to data from the Baryon Oscillation Spectroscopic Survey including new measurements of the matter density from Pantheon+.

Among other things I worked on forecasting the ability of improving on the measurement presented here with future observations.

I contributed flux denisty scale confirmation to this catalog of point sources extracted from data taken by the Atacama Cosmology Telescope.
