Milky Way's thick and thin disk: Is there a distinct thick disk? [PDF]

open access: yesAstronomische Nachrichten, 2016
AbstractThis article is based on our discussion session on Milky Way models at the 592 WE‐Heraeus Seminar, Reconstructing the Milky Way's History: Spectroscopic Surveys, Asteroseismology and Chemodynamical Models. The discussion focused on the following question: “Are there distinct thick and thin disks?”.

Ultrafast thin disk lasers: sub-100 fs pulse duration and carrier envelope offset detection

open access: yesEPJ Web of Conferences, 2013
We present two milestone results that confirm that thin disk lasers are excellent candidates for driving extreme nonlinear optics experiments. In a first experiment using the broadband mixed sesquioxide gain material Yb:LuScO3, we demonstrate that thin ...

The Stellar Population of the Thin Disk [PDF]

open access: yesProceedings of the International Astronomical Union, 2009
AbstractWe discuss recent observations of stars located close to the symmetry plane of the Milky Way, and examine them in the context of theories of Galaxy formation and evolution. The kinematics, ages, and compositions of thin disk stars in the solar neighborhood display complex patterns, and interesting correlations.

Carrier-Envelope Offset Frequency Stabilization of a Thin-Disk Laser Oscillator via Depletion Modulation

open access: yesIEEE Photonics Journal, 2020
We present a novel concept for the stabilization of the carrier-envelope offset (CEO) frequency of femtosecond pulse trains from thin-disk laser oscillators by exploiting gain depletion modulation in the active gain region.

Near-Infrared Detection of a Super-Thin Disk in NGC 891 [PDF]

open access: yesApJ 773 (2013) 45, 2013
We probe the disk structure of the nearby, massive, edge-on spiral galaxy NGC 891 with sub-arcsecond resolution JHKs-band images covering ~+/-10 kpc in radius and +/-5 kpc in height. We measure intrinsic surface brightness profiles using realistic attenuation corrections constrained from near- and mid-infrared (Spitzer) color maps and three-dimensional

Kinematic and chemical components in the solar neighbourhood

open access: yesEPJ Web of Conferences, 2012
Abundance data on solar neighbourhood stars suggest the presence of chemically-distinct stellar components in the solar neighbourhood. When the abundances of Fe, α elements, and the r-process element Eu are considered together, stars separate neatly into
