NOEMA redshift measurements of bright Herschel galaxies
R. Neri, P. Cox, A. Omont +31
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 Surv…
Identifying Strong Lenses with Unsupervised Machine Learning using Convolutional Autoencoder
Ting-Yun Cheng, Nan Li, Christopher J. Conselice +3
In this paper we develop a new unsupervised machine learning technique comprised of a feature extractor, a convolutional autoencoder (CAE), and a clustering algorithm consisting of…
Spitzer catalog of Herschel-selected ultrared dusty, star-forming galaxies
Jingzhe Ma, Asantha Cooray, Hooshang Nayyeri +24
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 ($S_{500}…
The use of convolutional neural networks for modelling large optically-selected strong galaxy-lens samples
James Pearson, Nan Li, Simon Dye
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…
The molecular-gas properties in the gravitationally lensed merger HATLAS J142935.3-002836
Hugo Messias, Neil Nagar, Zhi-Yu Zhang +11
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…
CO, H2O, H2O+ line and dust emission in a z = 3.63 strongly lensed starburst merger at sub-kiloparsec scales
C. Yang, R. Gavazzi, A. Beelen +22
Using ALMA, we report high angular-resolution observations of the redshift z=3.63 galaxy, G09v1.97, one of the most luminous strongly lensed galaxies discovered by the H-ATLAS surv…
