Odessa Astronomical Publications, 2019 We present a study on the verifica- tion of Machine Learning methods to be applied for binary morphological classification of galaxies. With this aim we used the sample of 60561 galaxies from the SDSSDR9 survey with a redshift of 0 . 02 < z < 0 .

An infrared study of a sample of optically selected galaxies [PDF]
, 1987 Infrared and optical photometry of a complete sub-sample of 194 galaxies in the Anglo-Australian Redshift Survey is presented. The Colour-Redshift diagrams are constructed and used, in a self-consistent manner, to reduce the data to zero-redshift colours

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Secondary evolution of galaxies investigated by N-body simulations [PDF]
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

Quantitative Morphology and Color Gradients of E+A Galaxies in Distant Galaxy Clusters [PDF]
, 1997 Narrow band multifilter photometry of the galaxy populations of four galaxy clusters at z=0.4-0.5 has provided us with a sample of 73 E+A galaxies which are secure cluster members. For 34 of them HST images are available (WFPC2). We have determined surface brigthness profiles and by means of an exponential or r^1/4 law fit we have classified the ...

The nature and origin of disky elliptical galaxies [PDF]
, 2002 The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

Galaxy Zoo:dust in spiral galaxies [PDF]
, 2010 We investigate the effect of dust on spiral galaxies by measuring the inclination dependence of optical colours for 24 276 well-resolved Sloan Digital Sky Survey (SDSS) galaxies visually classified via the Galaxy Zoo project.

Advanced Robotics Research, EarlyView.WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

The Astrophysical JournalPoststarburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals, where active galactic nucleus (AGN) feedback is suggested as one of the processes responsible for the quenching.

The Kinematic Bimodality: Efficient Feedback and Cold Gas Deficiency in Slow-rotating Galaxies
The Astrophysical Journal Letters, 2023 The bimodality in the stellar spin of low-redshift (massive) galaxies, ubiquitously existing at all star formation levels and in diverse environments, suggests that galaxies grow and quench through two diverged evolutionary pathways.
