A Face-on View of Interstellar Dust in the Galactic Plane
Lin Zhang, Bingqiu Chen, Fei Qin +3
Interstellar dust is a fundamental component of the Milky Way, influencing star formation, galactic evolution, and observations across the electromagnetic spectrum. Using red clump…
Effective Theories of Redshift-Space Galaxy Peculiar Velocities
Shi-Fan Chen, Cullan Howlett, Yan Lai +1
We present predictions for redshift-space peculiar velocity statistics in the Lagrangian and Eulerian formulations of the effective field theory (EFT) of large-scale structure. We…
The Redshift-Space Momentum Power Spectrum III: measuring the growth rate from the SDSSv survey using auto- and cross- power spectrum of the galaxy density and momentum fields
Fei Qin, Cullan Howlett, David Parkinson
The large-scale structure of the Universe and its evolution over time contains an abundance of cosmological information. One way to unlock this is by measuring the density and mome…
The MOST Hosts Survey: spectroscopic observation of the host galaxies of ~40,000 transients using DESI
Maayane T. Soumagnac, Peter Nugent, Robert A. Knop +54
We present the MOST Hosts survey (Multi-Object Spectroscopy of Transient Hosts). The survey is planned to run throughout the five years of operation of the Dark Energy Spectroscopi…
Constructing the three-dimensional extinction density maps using V-net
Bingqiu Chen, Fei Qin, Guangxing Li
One of the major challenges we face is how to quickly and accurately create the three-dimensional (3D) density distributions of interstellar dust in the Milky Way using extinction…
The Galaxy Number Density Profile of Haloes
Fei Qin, David Parkinson, Adam R. H. Stevens +1
More precise measurements of galaxy clustering will be provided by the next generation of galaxy surveys such as DESI, WALLABY and SKA. To utilize this information to improve our u…
Target Selection for the DESI Peculiar Velocity Survey
Christoph Saulder, Cullan Howlett, Kelly A. Douglass +35
We describe the target selection and characteristics of the DESI Peculiar Velocity Survey, the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP) and…
Reconstructing the cosmological density and velocity fields from redshifted galaxy distributions using V-net
Fei Qin, David Parkinson, Sungwook E. Hong +1
The distribution of matter that is measured through galaxy redshift and peculiar velocity surveys can be harnessed to learn about the physics of dark matter, dark energy, and the n…
HI HOD -- I. The Halo Occupation Distribution of HI Galaxies
Fei Qin, Cullan Howlett, Adam R. H. Stevens +1
The next generation of galaxy surveys will provide more precise measurements of galaxy clustering than have previously been possible. The 21-cm radio signals that are emitted from…
A measurement of the Integrated Sachs-Wolfe Effect with the Rapid ASKAP Continuum Survey
Benedict Bahr-Kalus, David Parkinson, Jacobo Asorey +3
The evolution of the gravitational potentials on large scales due to the accelerated expansion of the Universe is an important and independent probe of dark energy, known as the in…
The Sloan Digital Sky Survey Peculiar Velocity Catalogue
Cullan Howlett, Khaled Said, John R. Lucey +5
We present a new catalogue of distances and peculiar velocities (PVs) of early-type galaxies derived from Fundamental Plane (FP) measurements using data from the Sloan Dig…
Cosmic Flow Measurement and Mock Sampling Algorithm of Cosmicflows-4 Tully-Fisher Catalogue
Fei Qin, David Parkinson, Cullan Howlett +1
Measurements of cosmic flows enable us to test whether cosmological models can accurately describe the evolution of the density field in the nearby Universe. In this paper, we meas…
Gaussianization of peculiar velocities and bulk flow measurement
Fei Qin
The line-of-sight peculiar velocities are good indicators of the gravitational fluctuation of the density field. Techniques have been developed to extract cosmological information…
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_{…

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…
Bulk flow and shear in the local Universe: 2MTF and COSMICFLOWS-3
Fei Qin, Cullan Howlett, Lister Staveley-Smith +1
The low-order kinematic moments of galaxies, namely bulk flow and shear, enables us to test whether theoretical models can accurately describe the evolution of the mass density fie…
