Splitting the lentils: Clues to galaxy/black hole coevolution from the discovery of offset relations for non-dusty versus dusty (wet-merger-built) lenticular galaxies in the Mbh-M*, spheroid and Mbh-M*, galaxy diagrams [PDF]
Monthly notices of the Royal Astronomical Society, 2023 This work advances the (galaxy morphology)-dependent (black hole mass, Mbh)-(spheroid/galaxy stellar mass, M*) scaling relations by introducing ‘dust bins’ for lenticular (S0) galaxies.

Resequencing the Hubble sequence and the quadratic (black hole mass)–(spheroid stellar mass) relation for elliptical galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2023 One of the most protracted problems in astronomy has been understanding the evolution of galaxy morphology. Much discussion has surrounded how lenticular galaxies may form a bridging population between elliptical and spiral galaxies.

Brain and Behavior, Volume 13, Issue 2, February 2023., 2023 Graph 1. The receiver operating characteristic (ROC) curve. The area under the curve is 0.91 with a confidence interval (CI) of 95%: 0.84–0.97. The best substantia nigra cutoff value was 0.20 cm2. Sensitivity = 0.98 and specificity = 0.87. Abstract Objective The aim of this study is to compare a portable ultrasound (US) device and a traditional US for ...

Sedimentology, Volume 69, Issue 5, Page 2284-2318, August 2022., 2022 Abstract The sedimentary record of the Pahrump Group in Death Valley comprises well‐exposed successions of mixed carbonate and siliciclastic deposits. Despite the abundance of studies focussing on the depositional dynamics of mixed carbonate – siliciclastic deposition in the Phanerozoic, the record of similar Proterozoic examples is comparatively ...

The Halos and Environments of Nearby Galaxies (HERON) survey. IV. Complexity in the boxy galaxies NGC 720 and NGC 2768 [PDF]
Astronomy & Astrophysics, 2023 The shapes of galaxies, their outer regions in particular, are important guideposts to their formation and evolution. In this work, we report on the discovery of strongly box-shaped morphologies of the otherwise well-studied elliptical and lenticular ...

Aging of galaxies along the morphological sequence, marked by bulge growth and disk quenching [PDF]
Astronomy & Astrophysics, 2022 We revisit the color bimodality of galaxies using the extensive EFIGI morphological classification of nearby galaxies. The galaxy SDSS images in the g, r and i bands are decomposed as bulge+disk using SourceXtractor++.

Morphology, colour-magnitude and scaling relations of galaxies in Abell 426 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We present photometric properties of 183 member galaxies in the Abell 426 cluster using the Sloan Digital Sky Survey (SDSS) imaging and spectroscopic observation.

Morphological classification of galaxies with deep learning: comparing 3-way and 4-way CNNs [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Classifying the morphologies of galaxies is an important step in understanding their physical properties and evolutionary histories. The advent of large-scale surveys has hastened the need to develop techniques for automated morphological ...

Transforming gas-rich low-mass disky galaxies into ultra-diffuse galaxies by ram pressure [PDF]
Nature Astronomy, 2021 Faint extended elliptically shaped ultra-diffuse galaxies and slightly brighter and more compact dwarf elliptical and lenticular stellar systems are common in galaxy clusters.
