Dark Matter in Spiral Galaxies [PDF]
Symposium - International Astronomical Union, 1995 In this review I will concentrate on three questions concerning the issue of dark matter in spiral galaxies. In the first place (and for the most part) I will discuss the analysis of rotation curves and the question whether the “maximum–disk hypothesis” is valid.

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 ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Towards an Algorithmic Guide to Spiral Galaxies [PDF]
Theoretical Computer Science, 2014 In this paper, we are interested in the one-player game Spiral Galaxies, and study it from an algorithmic viewpoint. Spiral Galaxies has been shown to be NP-hard [Friedman, 2002] more than a decade ago, but so far it seems that no one has dared exploring its algorithmic universe. We take this trip and visit some of its corners.

Exploring the star formation histories of galaxies [PDF]
, 1999 In this thesis, I explore the star formation histories of both spiral and elliptical galaxies. In Part 1,1 present an in-depth study of the star formation histories of spiral galaxies with a wide range of properties. Optical and near-infrared colours are

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research
Reviews of Geophysics, Volume 64, Issue 3, September 2026.Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Do spiral arms enhance star formation efficiency? [PDF]
Spiral arms, as those of our own Milky Way, are some of the most spectacular features in disc galaxies. It has been argued that star formation should proceed more efficiently in spiral arms as a result of gas compression.
