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

Reports in Advances of Physical Sciences, 2023 Birkhoff’s theorem (1923) states that in the framework of General Relativity the only solution to the central symmetric gravitational field in vacuum is the Schwarzschild metric.

Galaxy Zoo:reproducing galaxy morphologies via machine learning [PDF]
, 2009 We present morphological classifications obtained using machine learning for objects in SDSS DR6 that have been classified by Galaxy Zoo into three classes, namely early types, spirals and point sources/artifacts.

Redshifts of the Gravitational Lenses MG0414+0534 and MG0751+2716 [PDF]
, 1998 We report redshifts in two gravitational lens systems, MG0414+0534 and MG0751+2716. The lens galaxy in MG0414+0534 lies at z_l=0.9584+/-0.0002. The luminosity and extreme red color of the lens are then typical of a passively evolving, early-type, ~2L ...

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.

Proceedings of the National Academy of Sciences, 1998 It is argued that within the standard Big Bang cosmological model the bulk of the mass of the luminous parts of the large galaxies likely had been assembled by redshift z ∼ 10. Galaxy assembly this early would be difficult to fit in the widely discussed adiabatic cold dark matter model for structure formation ...
