Small scale systems of galaxies . I . Photometric and spectroscopic properties of members
This paper is the first of a series addressed to the investigation of galaxy formation/evolution in small scale systems of galaxies (SSSGs) which are located in low density cosmic environments. Our algorithm for SSSG selection, includes galaxy systems of 2 or more galaxies lying within ∆cz≤ 1000 km s−1 and a 200 h−1 100 kpc radius volume. We present the analysis of the photometric and spectrosc...
متن کاملSmall-Scale Creative Systems
Creative computational systems have often been largescale endeavors, based on elaborate models of creativity and sometimes featuring an accumulation of heuristics and numerous subsystems. An argument is presented for facilitating the exploration of creativity through small-scale systems, which can be more transparent, reusable, focused, and easily generalized across domains and languages. These...
متن کاملFormation of dwarf galaxies and small-scale problems of CDM
The concordance cosmological model based on cold dark matter makes definitive predictions for the growth of galaxies in the Universe, which are being actively studied using numerical simulations. These predictions appear to contradict the observations of dwarf galaxies. Dwarf dark matter halos are more numerous and have steeper central density profiles than the observed galaxies. The first of t...
متن کامل1 Large - Scale , Small - Scale Systems
The objective of the project is to examine recent progress in two major areas of research – computer science and neuroscience, and their related fields – and to understand whether progress in understanding cognition in living systems has new insights to offer those researching the construction of artificial cognitive systems. * Authors listed in alphabetical order. Authorship of specific sectio...
متن کاملSmall-Scale Structure, Missing Galaxies and Gravitational Lensing
The gravitational lensing constraints on the small mass end of the ΛCDM mass function are discussed. Here a conservative approach is taken where only the most difficult to explain image flux anomalies in strong QSO lenses are emphasized. Numerical simulations are performed to compare predictions for the ΛCDM small scale mass function with the observed flux ratios. It is found that the cusp caus...
