Light Elements in the Universe
Frontiers in Astronomy and Space Sciences, 2021 Due to their production sites, as well as to how they are processed and destroyed in stars, the light elements are excellent tools to investigate a number of crucial issues in modern astrophysics: from stellar structure and non-standard processes at work

Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Main Galaxy Sample [PDF]
, 2002 We describe the algorithm that selects the main sample of galaxies for spectroscopy in the Sloan Digital Sky Survey (SDSS) from the photometric data obtained by the imaging survey.

Counterrotation in Galaxies [PDF]
Symposium - International Astronomical Union, 1999 The phenomenon of counterrotation is observed when two galaxy components have their angular momenta projected antiparallel onto the sky. It follows that if the two components rotate around the same axis, the counter-rotation is intrinsic. On the contrary the counterrotation is only apparent if the rotation axes are misaligned and the line-of-sight lies

First results from the IllustrisTNG simulations: the galaxy colour bimodality [PDF]
, 2017 We introduce the first two simulations of the IllustrisTNG project, a next generation of cosmological magnetohydrodynamical simulations, focusing on the optical colors of galaxies.

Meniscus Root Tear: Extended Classification and Arthroscopic Repair Techniques
Arthroscopy TechniquesThe meniscus root is an attachment of the anterior and posterior horns of the meniscus onto the tibia, and its primary function is to prevent extrusion under axial load. Meniscus root tear constitutes 15% to 20% of meniscus tear.

Metric completions, the Heine-Borel property, and approachability
Open Mathematics, 2020 We show that the metric universal cover of a plane with a puncture yields an example of a nonstandard hull properly containing the metric completion of a metric space.

A Heuristic Evaluation of Partitioning Techniques Considering Early-Type Galaxy Databases
Engineering Proceedings, 2023 Galaxies are one of the most interesting and complex astronomical objects statistically due to their continuous diversification caused mainly due to incidents such as accretion, action, or mergers. Multivariate studies are one of the most useful tools to

The clustering of the SDSS DR7 Main Galaxy Sample I: a 4 per cent distance measure at z=0.15 [PDF]
, 2014 We create a sample of spectroscopically identified galaxies with z < 0.2 from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7), covering 6813 deg(2).

KiDS+VIKING+GAMA: Testing semi-analytic models of galaxy evolution with galaxy–galaxy–galaxy lensing [PDF]
Astronomy & Astrophysics, 2020 Context. Several semi-analytic models (SAMs) try to explain how galaxies form, evolve, and interact inside the dark matter large-scale structure. These SAMs can be tested by comparing their predictions for galaxy–galaxy–galaxy lensing (G3L), which is weak gravitational lensing around galaxy pairs, with observations. Aims.
