A neutrino model fit to the CMB power spectrum (2014)
Journal Article
Shanks, T., Johnson, R., Schewtschenko, J., & Whitbourn, J. (2014). A neutrino model fit to the CMB power spectrum. Monthly Notices of the Royal Astronomical Society, 445(3), 2836-2841. https://doi.org/10.1093/mnras/stu1956

The standard cosmological model, Λ cold dark matter (ΛCDM), provides an excellent fit to cosmic microwave background (CMB) data. However, the model has well-known problems. For example, the cosmological constant, Λ, is fine-tuned to 1 part in 10100 a... Read More about A neutrino model fit to the CMB power spectrum.

Metal-enriched, subkiloparsec gas clumps in the circumgalactic medium of a faint z = 2.5 galaxy (2014)
Journal Article
Crighton, N., Hennawi, J., Simcoe, R., Cooksey, K., Murphy, M., Fumagalli, M., …Shanks, T. (2015). Metal-enriched, subkiloparsec gas clumps in the circumgalactic medium of a faint z = 2.5 galaxy. Monthly Notices of the Royal Astronomical Society, 446(1), 18-37. https://doi.org/10.1093/mnras/stu2088

We report the serendipitous detection of a 0.2 L*, Lyα emitting galaxy at redshift 2.5 at an impact parameter of 50 kpc from a bright background QSO sightline. A high-resolution spectrum of the QSO reveals a partial Lyman-limit absorption system (NHi...

The Very Large Telescope Lyman-Break Galaxy Redshift Survey – IV. Gas and galaxies at z ∼ 3 in observations and simulations (2014)
Journal Article
Tummuangpak, P., Bielby, R., Shanks, T., Theuns, T., Crighton, N., Francke, H., & Infante, L. (2014). The Very Large Telescope Lyman-Break Galaxy Redshift Survey – IV. Gas and galaxies at z ∼ 3 in observations and simulations. Monthly Notices of the Royal Astronomical Society, 442(3), 2094-2115. https://doi.org/10.1093/mnras/stu828

We use a combination of observations and simulation to study the relationship between star-forming galaxies and the intergalactic medium at z ≈ 3. The observed star-forming galaxy sample is based on spectroscopic redshift data taken from a combinatio... Read More about The Very Large Telescope Lyman-Break Galaxy Redshift Survey – IV.

Discovery of a cold stellar stream in the ATLAS DR1 data (2014)
Journal Article
Koposov, S., Irwin, M., Belokurov, V., Gonzales-Solares, E., Kupcu Yoldas, A., Lewis, J., …Shanks, T. (2014). Discovery of a cold stellar stream in the ATLAS DR1 data. Monthly Notices of the Royal Astronomical Society: Letters, 442(1), L85-L89. https://doi.org/10.1093/mnrasl/slu060

We report the discovery of a narrow stellar stream crossing the constellations of Sculptor and Fornax in the Southern celestial hemisphere. The portion of the stream detected in the Data Release 1 photometry of the ATLAS survey is at least 12° long,... Read More about Discovery of a cold stellar stream in the ATLAS DR1 data.

ATLAS lifts the Cup: discovery of a new Milky Way satellite in Crater (2014)
Journal Article
Belokurov, V., Irwin, M., Koposov, S., Evans, N., Gonzalez-Solares, E., Metcalfe, N., & Shanks, T. (2014). ATLAS lifts the Cup: discovery of a new Milky Way satellite in Crater. Monthly Notices of the Royal Astronomical Society, 441(3), 2124-2133. https://doi.org/10.1093/mnras/stu626

We announce the discovery of a new Galactic companion found in data from the ESO VST ATLAS survey, and followed up with deep imaging on the 4-m William Herschel Telescope. The satellite is located in the constellation of Crater (the Cup) at a distanc... Read More about ATLAS lifts the Cup: discovery of a new Milky Way satellite in Crater.

Search for primordial non-Gaussianity in the quasars of SDSS-III BOSS DR9 (2014)
Journal Article
Karagiannis, D., Shanks, T., & Ross, N. (2014). Search for primordial non-Gaussianity in the quasars of SDSS-III BOSS DR9. Monthly Notices of the Royal Astronomical Society, 441(1), 486-502. https://doi.org/10.1093/mnras/stu590

We analyse the clustering of 22 361 quasars between redshift 2.2 < z < 2.9 observed with the Sloan Digital Sky Survey (SDSS)-III Baryon Oscillation Spectroscopic Survey (BOSS), which are included in the ninth data release (DR9). We fit the clustering... Read More about Search for primordial non-Gaussianity in the quasars of SDSS-III BOSS DR9.

The local hole revealed by galaxy counts and redshifts (2014)
Journal Article
Whitbourn, J., & Shanks, T. (2014). The local hole revealed by galaxy counts and redshifts. Monthly Notices of the Royal Astronomical Society, 437(3), 2146-2162. https://doi.org/10.1093/mnras/stt2024

The redshifts of ≈250 000 galaxies are used to study the local hole and its associated peculiar velocities. The sample, compiled from the 6dF Galaxy Redshift Survey and Sloan Digital Sky Survey, provides wide sky coverage to a depth of ≈300 h−1 Mpc....
