First Results from SMAUG: The Need for Preventative Stellar Feedback and Improved Baryon Cycling in Semianalytic Models of Galaxy Formation [PDF]

Astrophysical Journal, 2020
Semianalytic models (SAMs) are a promising means of tracking the physical processes associated with galaxy formation, but many of their approximations have not been rigorously tested.

From theoretical stellar spectra to realistic models of the Milky Way : a never ending Odyssey [PDF]

, 2007
The last chapter is dedicated to the compilation of the results and the discussion about the success of - but also about the problems that have arisen during - and in part also survived - this work. The main goal of this thesis was, firstly, to convert

Feedback and the formation of dwarf galaxy stellar haloes [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
Stellar population studies show that low mass galaxies in all environments exhibit stellar halos that are older and more spherically distributed than the main body of the galaxy. In some cases, there is a significant intermediate age component that extends beyond the young disk. We examine a suite of Smoothed Particle Hydrodynamic (SPH) simulations and

Modeling for Stellar Feedback in Galaxy Formation Simulations [PDF]

The Astrophysical Journal, 2017
Abstract Various heuristic approaches to model unresolved supernova (SN) feedback in galaxy formation simulations exist to reproduce the formation of spiral galaxies and the overall inefficient conversion of gas into stars. Some models, however, require resolution-dependent scalings.

Disruption of giant molecular clouds and formation of bound star clusters under the influence of momentum stellar feedback [PDF]

Monthly notices of the Royal Astronomical Society, 2019
Energetic feedback from star clusters plays a pivotal role in shaping the dynamical evolution of giant molecular clouds (GMCs). To study the effects of stellar feedback on the star formation efficiency of the clouds and the dynamical response of ...

Disentangling planetary orbits from stellar activity in radial-velocity surveys [PDF]

, 2013
The majority of extra-solar planets have been discovered (or confirmed after follow-up) through radial-velocity (RV) surveys. Using ground-based spectrographs such as High Accuracy Radial Velocity Planetary Search (HARPS) and HARPS-North, it is now ...

Effects of Stellar Feedback on Stellar and Gas Kinematics of Star-forming Galaxies at 0.6 < z < 1.0 [PDF]

Astrophysical Journal, 2020
Recent zoom-in cosmological simulations have shown that stellar feedback can flatten the inner density profile of the dark matter halo in low-mass galaxies.
