Towards AMR Simulations of Galaxy Formation [PDF]
, 2010 Numerical simulations present a fundamental building block of our modern theoretical understanding of the Universe. As such the work in this thesis is primarily concerned with understanding fundamental differences that lie between the different ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Candidate Members of the VMP/EMP Disk System of the Galaxy from the SkyMapper and SAGES Surveys
The Astrophysical Journal Supplement SeriesPhotometric stellar surveys now cover a large fraction of the sky, probe to fainter magnitudes than large-scale spectroscopic surveys, and are relatively free from the target selection biases often associated with such studies.

, 2012 We briefly describe TRILEGAL, a TRIdimensional modeL of thE GALaxy, and its more recent developments. Particularly relevant is the recent inclusion of a kinematical module to the code, and the present efforts to provide a more solid calibration of Milky ...

Mass extinction and the structure of the milky way [PDF]
, 2013 We use the most up-to-date Milky Way model and solar orbit data in order to test the hypothesis that the Sun's galactic spiral arm crossings cause mass extinction events on Earth. To do this, we created a new model of the Milky Way's spiral arms

Additional Evidence for the Existence of a Primordial Disk System
The Astrophysical JournalThe origin of very metal-poor (VMP; [Fe/H] ≤ −2.0) stars on planar orbits has been the subject of great attention since their first discovery. However, prior to the release of the Gaia BP/RP (XP) spectra and large photometric samples such as SkyMapper ...

Terraforming the Milky Way galaxy
, 2023 After terraforming the entire Milky Way galaxy, create habitats in two phases: 1.Create a habitat in the entire Solar System only for humans to live in. 2.Create a habitat in the remaining (terraformed) galaxy for all the non-human creatures resurrected on Earth and transport them using mega spaceships.

What Is Missing from the Local Stellar Halo?
The Astrophysical JournalThe Milky Way’s stellar halo, which extends to >100 kpc, encodes the evolutionary history of our Galaxy. However, most studies of the halo to date have been limited to within a few kiloparsecs of the Sun.

Simulating supernova feedback in galaxy disks [PDF]
, 2012 In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

Icarus Revisited: An Ancient, Metal-poor Accreted Stellar Stream in the Disk of the Milky Way
The Astrophysical JournalThe search for accreted satellites in the Galactic disk is a challenging task, to which Gaia plays a crucial role in synergy with ground-based spectroscopic surveys. In 2021, P. Re Fiorentin et al.
