Kinematic Modeling of Distant Galaxies
Open Astronomy, 2012 Evolution of galaxies is one of the most actual topics in astrophysics. Among the most important factors determining the evolution are two galactic components which are difficult or even impossible to detect optically: the gaseous disks and the dark ...

Hydrostatics of the Galactic Halo
, 1998 We investigated a hydrostatic equilibrium model of the Milky Way following Parker (1966), to constrain the large scale properties of the interstellar medium. In our approach we found an excellent agreement between our simple hydrostatic equilibrium model of the Milky Way and the recent all-sky survey data rangeing from the gamma-ray to the radio regime.

Galactic versus Extragalactic Pixel Lensing Events toward M31 [PDF]
, 1996 A new type of gravitational microlensing experiment toward a field where stars are not resolved is being developed observationally and theoretically: pixel lensing. When the experiment is carried out toward the M31 bulge area, events may be produced both by Massive Compact Halo Objects (MACHOs) in our Galactic halo and by lenses in M31.

Advanced Materials Interfaces, EarlyView.This research explores local bandgap, composition, and strain variations across InxGa₁−xAs quantum wells within a metamorphic laser structure using high‐resolution scanning transmission electron microscopy (STEM) and low‐loss electron energy loss spectroscopy (EELS). Results reveal significant inhomogeneities, particularly near interfaces, with bandgap

Are dSph galaxies Galactic building blocks?
EPJ Web of Conferences, 2012 Dwarf spheroidal galaxies (dSph) are frequently assumed to represent surviving examples of a vast now destroyed population of small systems in which many of the stars now forming the Milky Way were formed. Ongoing accretion and considerable sub-structure

The Galactic Halo: Conference Summary [PDF]
arXiv, 1999 This summary discusses new results on the stellar and gaseous luminous halo, and on the dark halo. It concludes with a look towards the future, with emphasis on the role of space astrometry missions.

Ultrathin Gold for Robust Multi‐Element Surface Plasmon Resonance Biosensing
Advanced Materials Interfaces, EarlyView.This is a pioneering work where for the first time we applied recently synthesised ultrathin layer of gold for plasmonic biosensing that makes use of multi‐element architectures. This study solves the problem of stability of the multi‐element biosensors as well as demonstrates increased sensitivity achieved by utilising new additions to low‐dimension ...

The Galactic Halo from Microlensing [PDF]
, 2002 The status of the microlensing search for galactic dark matter in the form of massive astronomical compact halo objects (machos) is reviewed. Unresolved issues are discussed, as well as possible ways to solve these.

Globular cluster contributions to Galactic halo assembly [PDF]
arXiv, 2012 I discuss a search for red giant stars in the Galactic halo with light-element abundances similar to second-generation globular cluster stars, and discuss the implications of such a population for globular cluster formation models and the balance between in situ star formation and accretion for the assembly of the Galactic halo.

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks
Advanced Materials Interfaces, EarlyView.All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.
