A Novel high-z submm Galaxy Efficient Line Survey in ALMA bands 3 through 8 -- An ANGELS Pilot
T. J. L. C. Bakx, A. Amvrosiadis, G. J. Bendo +32
We use the Atacama Large sub/Millimetre Array (ALMA) to efficiently observe spectral lines across Bands 3, 4, 5, 6, 7, and 8 at high-resolution (0.5" - 0.1") for 16 bright southern…
Galaxy Mass Modelling from Multi-Wavelength JWST Strong Lens Analysis: Dark Matter Substructure, Angular Mass Complexity, or Both?
Samuel C. Lange, Aristeidis Amvrosiadis, James W. Nightingale +8
We analyze two galaxy-scale strong gravitational lenses, SPT0418-47 and SPT2147-50, using JWST NIRCam imaging across multiple filters. To account for angular complexity in the lens…
SCUBADive I: JWST+ALMA Analysis of 289 sub-millimeter galaxies in COSMOS-Web
Jed McKinney, Caitlin M. Casey, Arianna S. Long +36
JWST has enabled detecting and spatially resolving the heavily dust-attenuated stellar populations of sub-millimeter galaxies, revealing detail that was previously inaccessible. In…
Lopsidedness in Early-Type Galaxies: the role of the multipole in Isophote Fitting and Strong Lens Modelling
Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +6
The surface brightness distribution of massive early-type galaxies (ETGs) often deviates from a perfectly elliptical shape. To capture these deviations in their isophotes during an…
The onset of bar formation in a massive galaxy at
Aristeidis Amvrosiadis, Samuel Lange, James Nightingale +13
We examine the morphological and kinematical properties of SPT-2147, a strongly lensed, massive, dusty, star-forming galaxy at . Combining data from JWST, HST, and ALMA,…
Unveiling Lens Light Complexity with A Novel Multi-Gaussian Expansion Approach for Strong Gravitational Lensing
Qiuhan He, James W. Nightingale, Aris Amvrosiadis +8
In a strong gravitational lensing system, the distorted light from a source is analysed to infer the properties of the lens. However, light emitted by the lens itself can contamina…
