Galaxy 2-Point Covariance Matrix Estimation for Next Generation Surveys
Cullan Howlett, Will J. Percival
We perform a detailed analysis of the covariance matrix of the spherically averaged galaxy power spectrum and present a new, practical method for estimating this within an arbitrar…
Measuring the growth rate of structure with Type IA Supernovae from LSST
Cullan Howlett, Aaron S. G. Robotham, Claudia D. P. Lagos +1
We investigate measuring the peculiar motions of galaxies up to using Type Ia supernovae (SNe Ia) from LSST, and predict the subsequent constraints on the growth rate of st…
2MTF VI. Measuring the velocity power spectrum
Cullan Howlett, Lister Staveley-Smith, Pascal J. Elahi +7
We present measurements of the velocity power spectrum and constraints on the growth rate of structure , at redshift zero, using the peculiar motions of 2,062 galaxies in t…
