Barry and the BAO Model Comparison
Samuel R. Hinton, Cullan Howlett, Tamara M. Davis
We compare the performance of four state-of-the-art models for extracting isotropic measurements of the Baryon Acoustic Oscillation (BAO) scale. To do this, we created a new, publi…
Multi-wavelength consensus of large-scale linear bias
Hengxing Pan, Danail Obreschkow, Cullan Howlett +4
We model the large-scale linear galaxy bias as a function of redshift and observed absolute magnitude threshold for broadband continuum emission from the far inf…
Standard Siren Speeds: Improving velocities in gravitational-wave measurements of
Cullan Howlett, Tamara M. Davis
We re-analyze data from the gravitational-wave event GW170817 and its host galaxy NGC4993 to demonstrate the importance of accurate total and peculiar velocities when measuring the…
Can redshift errors bias measurements of the Hubble Constant?
Tamara M. Davis, Samuel R. Hinton, Cullan Howlett +1
Redshifts have been so easy to measure for so long that we tend to neglect the fact that they too have uncertainties and are susceptible to systematic error. As we strive to measur…
The Redshift-Space Momentum Power Spectrum I: Optimal Estimation From Peculiar Velocity Surveys
Cullan Howlett
Low redshift surveys of galaxy peculiar velocities provide a wealth of cosmological information. We revisit the idea of extracting this information by directly measuring the redshi…
The Redshift Space Momentum Power Spectrum II: measuring the growth rate from the combined 2MTF and 6dFGSv surveys
Fei Qin, Cullan Howlett, Lister Staveley-Smith
Measurements of the growth rate of structure, in the low-redshift Universe allow stringent tests of the cosmological model. In this work, we provide new constraints on $fσ_{…
2MTF - VII. 2MASS Tully-Fisher survey final data release: distances for 2,062 nearby spiral galaxies
Tao Hong, Lister Staveley-Smith, Karen L. Masters +8
We present the final distance measurements for the 2MASS Tully-Fisher (2MTF) survey. The final 2MTF catalogue contains 2,062 nearby spiral galaxies in the CMB frame velocity range…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
4MOST Consortium Survey 8: Cosmology Redshift Survey (CRS)
J. Richard, J. -P. Kneib, C. Blake +14
The 4MOST Cosmology Redshift Survey (CRS) will perform stringent cosmological tests via spectroscopic clustering measurements that will complement the best lensing, cosmic microwav…
4MOST: Project overview and information for the First Call for Proposals
R. S. de Jong, O. Agertz, A. Agudo Berbel +335
We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Vis…
Cosmology with the MaunaKea Spectroscopic Explorer
Will J. Percival, Christophe Yèche, Maciej Bilicki +11
This document summarizes the science cases related to cosmology studies with the MaunaKea Spectroscopic Explorer (MSE), a highly-multiplexed (4332 fibers), wide FOV (1.5 sq deg), l…
Testing Gravity Using Type Ia Supernovae Discovered by Next-Generation Wide-Field Imaging Surveys
A. G. Kim, G. Aldering, P. Antilogus +29
In the upcoming decade cadenced wide-field imaging surveys will increase the number of identified Type~Ia supernovae (SNe~Ia) from the hundreds to the hundreds of thousands…
