Using the IRAM NOrthern Extended Millimeter Array (NOEMA), we conducted a program to measure redshifts for 13 bright galaxies detected in the Herschel Astrophysical Large Area Survey (H-ATLAS) with S500 _m _ 80 mJy. We report reliable spectroscopic r... Read More about NOEMA redshift measurements of bright Herschel galaxies.

Spitzer Catalog of Herschel-selected Ultrared Dusty Star-forming Galaxies (2019)
Journal Article
Ma, J., Cooray, A., Nayyeri, H., Ghotbi, N., Ivison, R., Brown, A., …Valiante, E. (2019). Spitzer Catalog of Herschel-selected Ultrared Dusty Star-forming Galaxies. Astrophysical Journal Supplement, 244(2), 1-19. https://doi.org/10.3847/1538-4365/ab4194

The largest Herschel extragalactic surveys, H-ATLAS and HerMES, have selected a sample of “ultrared” dusty, star-forming galaxies (DSFGs) with rising SPIRE flux densities (S500 > S350 > S250, so-called “500 μm-risers”) as an efficient way for identif...

The use of convolutional neural networks for modelling large optically-selected strong galaxy-lens samples (2019)
Journal Article
Pearson, J., Li, N., & Dye, S. (2019). The use of convolutional neural networks for modelling large optically-selected strong galaxy-lens samples. Monthly Notices of the Royal Astronomical Society, 488(1), 991-1004. https://doi.org/10.1093/mnras/stz1750

We explore the effectiveness of deep learning convolutional neural networks (CNNs) for estimating strong gravitational lens mass model parameters. We have investigated a number of practicalities faced when modelling real image data, such as how netwo...

Follow-up observations of (sub-)mm-selected gravitationally-lensed systems have allowed a more detailed study of the dust-enshrouded phase of star-formation up to very early cosmic times. Here, the case of the gravitationally lensed merger in HATLAS... Read More about The molecular-gas properties in the gravitationally lensed merger HATLAS J142935.3-002836.

Journal Article

We present the final results from our survey of luminous z ~ 5.5 quasars. This is the first systematic quasar survey focusing on quasars at z ~ 5.5, during the post-reionization epoch. It has been challenging to select quasars at 5.3 < z < 5.7 using... Read More about Filling in the Quasar Redshift Gap at z ∼ 5.5. II.
