Simulating Galaxy Clusters With Dust Formation And Evolution

, 2017
In order to investigate basic properties of galaxies, such as the star formation rate and the masses of baryonic components, it is important to account for dust reprocessing. Dust particles absorb and scatter the stars' optical/UV emission, and they re-radiate thermally in the infrared.

How Important Is the Home Market for Cross‐Listed Biotech Companies?

International Finance, EarlyView.
ABSTRACT This study investigates five German biotechnology firms cross‐listed on XETRA and NASDAQ. By employing high‐frequency data, we estimate both bivariate and trivariate vector error correction models—the latter explicitly accounting for exchange rate dynamics—to assess which market, domestic or U.S., leads in price discovery.

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal)

Astronomy & Astrophysics
The Milky Way’s inner region is dominated by a stellar bar and a boxy-peanut-shaped bulge. However, which stellar populations inhabit the inner Galaxy or how star formation proceeded there is still unknown.

The Formation and Evolution of Galaxies

, 1998
Galaxies represent the visible fabric of the Universe and there has been considerable progress recently in both observational and theoretical studies. The underlying goal is to understand the present-day diversity of galaxy forms, masses and luminosities.

Innovation Diffusion Among Case‐Based Decision‐Makers

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes a model of innovation diffusion with case‐based individuals a la Gilboa and Schmeidler, who decide whether to consume an incumbent or a new product based on their and their social neighbors' previous consumption experiences. I analyze how diffusion patterns change with individual characteristics, innovation characteristics,
