The accreted galaxy: An overview of TESS metal-poor accreted star candidates
Astronomy & AstrophysicsThe Milky Way is a mosaic of stars from different origins. In particular, metal-poor accreted star candidates offer a unique opportunity to better understand the accretion history of the Milky Way. In this work, we aim to explore the assembly history of the Milky Way by investigating accreted stars in terms of their ages, dynamical properties, and ...

THE ACCRETION GEOMETRY IN RADIO-LOUD ACTIVE GALAXIES [PDF]
Modern Physics Letters A, 2007 We review the latest attempts to determine the accretion geometry in radio-loud active galactic nuclei (AGN). These objects, which comprise ~ 10–20% of the AGN population, produce powerful collimated radio jets that can extend thousands of parsecs from the center of the host galaxy. Recent multiwavelength surveys have shown that radio-loudness is more

, 2021 In the two-phase scenario of galaxy formation, a galaxy's stellar mass growth is first dominated by in-situ star formation, and subsequently by accretion. We analyse the radial distribution of the accreted stellar mass in ~500 galaxies from the hydrodynamical cosmological simulation Magneticum.

Computers and chess masters: The role of AI in transforming elite human performance
British Journal of Psychology, EarlyView.Abstract Advances in Artificial Intelligence (AI) have made significant strides in recent years, often supplementing rather than replacing human performance. The extent of their assistance at the highest levels of human performance remains unclear. We analyse over 11.6 million decisions of elite chess players, a domain commonly used as a testbed for AI

Hydro-Gravitational Dynamics of Planets and Dark Energy
Journal of Applied Fluid Mechanics, 2009 Self gravitational fluid mechanical methods termed hydro-gravitational-dynamics (HGD) predict plasma fragmentation 0.03 Myr after the turbulent big bang to form protosuperclustervoids, turbulent protosuperclusters, and protogalaxies at the 0.3 Myr ...

The Astrophysical JournalHyper-luminous X-ray sources (HLXs) are extragalactic off-nuclear X-ray sources with luminosities exceeding the theoretical limit for accretion onto stellar-mass compact objects.

The Impact of Galactic Winds on the Angular Momentum of Disk Galaxies in the Illustris Simulation
, 2017 Observed galactic disks have specific angular momenta similar to expectations for typical dark matter halos in $\Lambda$CDM. Cosmological hydrodynamical simulations have recently reproduced this similarity in large galaxy samples by including strong ...

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,
