Journal Article
Neri, R., Cox, P., Omont, A., Beelen, A., Berta, S., Bakx, T., …Young, A. (2020). NOEMA redshift measurements of bright Herschel galaxies. Astronomy and Astrophysics, 635, Article A7. https://doi.org/10.1051/0004-6361/201936988

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...

The molecular-gas properties in the gravitationally lensed merger HATLAS J142935.3-002836 (2019)
Journal Article
Messias, H., Nagar, N., Zhang, Z., Oteo, I., Dye, S., Ibar, E., …Yang, C. (2019). The molecular-gas properties in the gravitationally lensed merger HATLAS J142935.3-002836. Monthly Notices of the Royal Astronomical Society, 486(2), 2366-2378. https://doi.org/10.1093/mnras/stz945

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
Yang, J., Wang, F., Fan, X., Wu, X., Bian, F., Bañados, E., …Dye, S. (2019). Filling in the Quasar Redshift Gap at z ∼ 5.5. II. A Complete Survey of Luminous Quasars in the Post-reionization Universe. Astrophysical Journal, 871(2), 199. https://doi.org/10.3847/1538-4357/aaf858

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.
