Disentangling the dark and stellar mass through precise lens modelling of the JWST observation of lensed quasar WFI2033--4723
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +2
We use high-resolution JWST/NIRCam imaging and measured time delays to model the quadruply imaged quasar WFI2033--4723 with a composite stellar plus dark-matter mass model. We firs…
How to Break the Mass Sheet Degeneracy with the Lightcurves of Microlensed Type Ia Supernovae
Luke Weisenbach, Thomas Collett, Ana Sainz de Murieta +4
The standardizable nature of gravitationally lensed Type Ia supernovae (glSNe Ia) makes them an attractive target for time delay cosmography, since a source with known luminosity b…
Galaxy Zoo: Clump Scout -- Design and first application of a two-dimensional aggregation tool for citizen science
Hugh Dickinson, Dominic Adams, Vihang Mehta +9
Galaxy Zoo: Clump Scout is a web-based citizen science project designed to identify and spatially locate giant star forming clumps in galaxies that were imaged by the Sloan Digital…
Galaxy Zoo: 3D -- Crowd-sourced Bar, Spiral and Foreground Star Masks for MaNGA Target Galaxies
Karen L. Masters, Coleman Krawczyk, Shoaib Shamsi +15
The challenge of consistent identification of internal structure in galaxies - in particular disc galaxy components like spiral arms, bars, and bulges - has hindered our ability to…
Galaxy Zoo Builder: Morphological Dependence of Spiral Galaxy Pitch Angle
Timothy Lingard, Karen L. Masters, Coleman Krawczyk +6
Spiral structure is ubiquitous in the Universe, and the pitch angle of arms in spiral galaxies provide an important observable in efforts to discriminate between different mechanis…
Galaxy Zoo DECaLS: Detailed Visual Morphology Measurements from Volunteers and Deep Learning for 314,000 Galaxies
Mike Walmsley, Chris Lintott, Tobias Geron +15
We present Galaxy Zoo DECaLS: detailed visual morphological classifications for Dark Energy Camera Legacy Survey images of galaxies within the SDSS DR8 footprint. Deeper DECaLS ima…
