Hierarchical Star Formation in the Spiral Galaxy NGC 628 [PDF]
, 2006 The distributions of size and luminosity for star-forming regions in the nearby spiral galaxy NGC 628 are studied over a wide range of scales using progressively blurred versions of an image from the Hubble Space Telescope Advanced Camera for Surveys ...

Plasticity of the heart in response to changes in physical activity
The Journal of Physiology, EarlyView.Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

The Primordial Origin Model of Magnetic Fields in Spiral Galaxies
, 2010 We propose a primordial-origin model for the composite configurations of global magnetic fields in spiral galaxies. We show that uniform tilted magnetic field wound up into a rotating disk galaxy can evolve into composite magnetic configurations ...

A dynamical model for the heavily ram pressure stripped Virgo spiral galaxy NGC 4522 [PDF]
, 2006 Context. Recent Hi and H α observations of NGC 4522 have revealed that this spiral galaxy represents one of the best cases of ongoing ram pressure stripping in the Virgo cluster. Aims.

Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract Current observations show that a significant fraction of the Universe is composed of dark energy and dark matter. In this paper, the simultaneous effects of these dark sectors on the Euler–Heisenberg black hole are investigated, using the quintessence matter field and perfect fluid to model them. In particular, the black hole's thermodynamics,

Tracing the Spiral Structure of the Outer Milky Way with Dense Atomic Hydrogen Gas
, 2017 We present a new face-on map of dense neutral atomic hydrogen (HI) gas in the outer Galaxy. Our map has been produced from the Leiden/Argentine/Bonn (LAB) HI 21-cm line all-sky survey by finding intensity maxima along every line of sight and then by ...

ESO 603-G21: A strange polar-ring galaxy
, 2001 We present the results of B, V, R surface photometry of ESO603-G21 - a galaxy with a possible polar ring. The morphological and photometric features of this galaxy are discussed.

Magnetic-Field Vector Maps of Nearby Spiral Galaxies
Galaxies, 2019 We present a method for determining the directions of magnetic-field vectors in a spiral galaxy using two synchrotron polarization maps, an optical image, and a velocity field.
