Discovering strongly lensed quasar candidates with catalogue-based methods from DESI Legacy Surveys

Autor: Zizhao He, Nan Li, Xiaoyue Cao, Rui Li, Hu Zou, Simon Dye

The Hubble tension, revealed by a $\sim 5\sigma$ discrepancy between measurements of the Hubble-Lemaitre constant from early- and local-Universe observations, is one of the most significant problems in modern cosmology. In order to better understand

(Abridged) Exploiting the sensitivity and broad band width of NOEMA, we have studied the molecular gas and dust in the galaxy HerBS-89a, at z=2.95. High angular resolution images reveal a partial 1.0" diameter Einstein ring in the dust continuum emis

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 $S_{500{\mu}\rm m}\ge$80 mJy. We report reliable spe

Identifying strong lenses with unsupervised machine learning using convolutional autoencoder

Autor: Christopher J. Conselice, R. B. Metcalf, Simon Dye, Ting-Yun Cheng, Alfonso Aragón-Salamanca, Nan Li

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 a Bayesian Gaussian mixture model (BGM). We apply this technique to v
