Summary: observations of stellar halos
, 2019 This presentation summarizes a (biased) selection of results and discussions presented during the Sexten 2019 workshop "Light in the suburbs: structure and chemodynamics of galaxy halos" based on observations. Over the past decade observations of stellar

The Stellar Halo of the Spiral Galaxy NGC 1560 [PDF]
The Astrophysical Journal, 2018 Abstract We report on the detection of a stellar halo around NGC 1560, a 109 M ⊙ spiral galaxy member of the Maffei group. We obtained deep images in the r- and i-bands using the 10.4 m Gran Telescopio Canarias in a field centered at ∼3.7 arcmin (projected distance of 3.5 kpc) from the center of this ...

Secondary evolution of galaxies investigated by N-body simulations [PDF]
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry
Agribusiness, EarlyView.ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Study of galaxy stellar halos and faint structures with VEGAS@VST
, 2018 Deep and large-scale multi-band imaging is crucial to study the galaxy outskirts, out to hundreds of kiloparsecs, where the imprints of the mass assembly reside: these are the regions of the stellar halos.

HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots
Advanced Intelligent Systems, EarlyView.A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

Advanced NanoBiomed Research, EarlyView.Fibroblast behavior is shaped by the surrounding microenvironment, yet conventional culture systems often fail to capture disease‐relevant phenotypes. Here, platform‐dependent responses of healthy and arthritic synovial fibroblasts are examined across 2D and 3D culture systems. Distinct inflammatory and proliferative signatures emerge, highlighting how

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
