Performance of morphological classifiers for galaxy mergers compared to current machine learning methods
Aidan P. Cotter, William J. Pearson, William J. pearson +4
Aims. Non-parametric morphological statistics can be used for efficient classification of galaxy mergers. This work aims to compare the performance of morphological merger classifi…
Super-resolving Herschel - a deep learning based deconvolution and denoising technique
Dennis Koopmans, Lingyu Wang, Berta Margalef-Bentabol +9
Dusty star-forming galaxies (DSFGs) dominate the far-infrared and sub-millimetre number counts, but single-dish surveys suffer from poor angular resolution, complicating mult-wavel…
Classifying merger stages with adaptive deep learning and cosmological hydrodynamical simulations
Rosa de Graaff, Berta Margalef-Bentabol, Lingyu Wang +4
Hierarchical merging of galaxies plays an important role in galaxy formation and evolution. Mergers could trigger key evolutionary phases such as starburst activities and active ac…
Probabilistic and progressive deblended far-infrared and sub-millimetre point source catalogues I. Methodology and first application in the COSMOS field
Lingyu Wang, Antonio La Marca, Fangyou Gao +12
Single-dish far-infrared (far-IR) and sub-millimetre (sub-mm) point source catalogues and their connections with catalogues at other wavelengths are of paramount importance. Howeve…
Observations of the Initial Formation and Evolution of Spiral galaxies at in the CANDELS fields
Berta Margalef-Bentabol, Christopher J. Conselice, Boris Haeussler +4
Many aspects concerning the formation of spiral and disc galaxies remain unresolved, despite their discovery and detailed study over the past years. As such, we present the r…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
The half mass radius of MaNGA galaxies: Effect of IMF gradients
M. Bernardi, R. K. Sheth, H. Dominguez Sanchez +3
Gradients in the stellar populations (SP) of galaxies -- e.g., in age, metallicity, stellar Initial Mass Function (IMF) -- can result in gradients in the stellar mass to light rati…
SDSS-IV MaNGA: drivers of stellar metallicity in nearby galaxies
Justus Neumann, Daniel Thomas, Claudia Maraston +12
The distribution of stellar metallicities within and across galaxies is an excellent relic of the chemical evolution across cosmic time. We present a detailed analysis of spatially…
The Fundamental Plane of Massive Quiescent Galaxies at z~2
Mikkel Stockmann, Inger Jørgensen, Sune Toft +11
We examine the Fundamental Plane (FP) and mass-to-light ratio () scaling relations using the largest sample of massive quiescent galaxies at to date. The FP ($r_{e…
The relationship between fine galaxy stellar morphology and star formation activity in cosmological simulations: a deep learning view
Lorenzo Zanisi, Marc Huertas-Company, Francois Lanusse +10
Hydrodynamical simulations of galaxy formation and evolution attempt to fully model the physics that shapes galaxies. The agreement between the morphology of simulated and real gal…
Galaxy properties as revealed by MaNGA. III. Kinematic profiles and stellar population gradients in S0s
H. Domínguez Sánchez, M. Bernardi, F. Nikakhtar +2
This is the third paper of a series where we study the stellar population gradients (SP; ages, metallicities, -element abundance ratios and stellar initial mass functions) of ea…
The Stellar Mass Fundamental Plane: The virial relation and a very thin plane for slow-rotators
M. Bernardi, H. Domínguez Sanchez, B. Margalef-Bentabol +2
Early-type galaxies -- slow and fast rotating ellipticals (E-SRs and E-FRs) and S0s/lenticulars -- define a Fundamental Plane (FP) in the space of half-light radius , enclosed…
Detecting outliers in astronomical images with deep generative networks
