THE MAGNESIUM ABUNDANCE IN THE THIN AND THICK DISK OF THE GALAXY
Odessa Astronomical Publications, 2017 The chemical evolution of the thin and thick disk of our Galaxy was investigated in framework of the opened model with gas inflow. It was supposed that the thin and thick disks separate chemically and spatially and have different evolution timescales ...

Structural and signaling proteins in the Z-disk and their role in cardiomyopathies
Frontiers in Physiology, 2023 The sarcomere is the smallest functional unit of muscle contraction. It is delineated by a protein-rich structure known as the Z-disk, alternating with M-bands.

The Panchromatic Hubble Andromeda Treasury. XX. The Disk of M31 is Thick
The Astronomical Journal, 2023 We present a new approach to measuring the thickness of a partially face-on stellar disk, using dust geometry. In a moderately-inclined disk galaxy, the fraction of reddened stars is expected to be 50% everywhere, assuming that dust lies in a thin ...

Femtosecond Yb:CaGdAlO_4 thin-disk oscillator [PDF]
Optics Letters, 2012 A mode-locked thin-disk laser based on Yb:CALGO is demonstrated for the first time. At an average output power of 28 W we obtained pulses with a duration of 300 fs and a pulse energy of 1.3 μJ. 197 fs pulses with 0.9 μJ of energy were achieved at an average output power of 20 W.

Optics Express, 2014 We present Ytterbium-doped CaF2 as a laser active material with good prospects for high-power operation in thin-disk laser configuration owing to its favorable thermal properties. Thanks to its broad emission bandwidth the material is also suitable for the generation of ultra-short pulses. The properties of the crystal as well as the challenges related

Thick Disks of Lenticular Galaxies [PDF]
Astron.Astrophys. 422 (2004) 465-475, 2004 Thick disks are faint and extended stellar components found around several disk galaxies including our Milky Way. The Milky Way thick disk, the only one studied in detail, contains mostly old disk stars (~10 Gyr), so that thick disks are likely to trace the early stages of disk evolution.

European Physical Journal C: Particles and Fields, 2021 We have studied polarized image of a Schwarzschild black hole with an equatorial thin accretion disk as photon couples to Weyl tensor. The birefringence of photon originating from the coupling affect the black hole shadow, the thin disk pattern and its ...

The Galactic thin and thick disk [PDF]
Astronomische Nachrichten, 2012 AbstractThe ongoing large spectroscopic surveys of the Milky Way such as SEGUE and RAVE have enabled us to take a fresh look at the structure of the Galactic thin and thick disks, and how their structure fits within the framework of structure formation via hierarchical clustering. In this article I will summarize some recent results mainly based in the
