The Multifrequency Astrophysics of Galaxy Clusters [PDF]

Chinese Journal of Astronomy and Astrophysics, 2003
We discuss the evidence and the physical relevance of the astrophysical phenomena (of thermal and non-thermal origin) occurring in galaxy clusters as obtained from multi-frequency observations, from radio to gamma-rays.

Local and large-scale effects on the astrophysics of void galaxies

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Galaxies in cosmic voids have been reported with properties related to a delayed evolution compared to the rest of the Universe. These characteristics reflect the interaction of galaxies with the environment. However, it is not clear the degree of influence of the large-scale structure on the properties of void galaxies or if ...

Spiral galaxies as enantiomers: Chirality, an underlying feature in chemistry and astrophysics [PDF]

Chirality, 2005
AbstractSpiral galaxies are axisymmetric objects showing 2D chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in amino acids and sugars. Environmental effects can influence the intrinsic chirality of originally isolated

Galaxy Winds in the Age of Hyperdimensional Astrophysics

, 2019
The past decade began with the first light of ALMA and will end at the start of the new era of hyperdimensional astrophysics. Our community-wide movement toward highly multiwavelength and multidimensional datasets has enabled immense progress in each science frontier identified by the 2010 Decadal Survey, particularly with regard to black hole feedback

Groups of galaxies in the Center for Astrophysics redshift survey

The Astrophysical Journal, 1989
By applying the Huchra and Geller (1982) objective group identification algorithm to the Center for Astrophysics' redshift survey, a catalog of 128 groups with three or more members is extracted, and 92 of these are used as a statistical sample. A comparison of the distribution of group centers with the distribution of all galaxies in the survey ...

Reification of galaxies: cognitive astrophysics and the multiwavelength inverse problem [PDF]

Proceedings of the International Astronomical Union, 2011
Lessons learned in the history and philosophy of science have generally had little immediate impact on how we as individual astronomers conduct our research. And yet we do share many common views on how we undertake basic research, and how we translate observations and theory into communicable knowledge.

Applications of the IGIMF-theory to the astrophysics of galaxies

, 2010
The functional form of the galaxy-wide stellar initial mass function is of fundamental importance for understanding galaxies. So far this stellar initial mass function has been assumed to be identical to the IMF observed directly in star clusters. But because stars form predominantly in embedded groups rather than uniformly distributed over the whole ...
