Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]
, 2005 Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

British Journal of Educational Psychology, EarlyView.Abstract Background This study investigated the development of primary school children's error‐related adjustments in reading and arithmetic, both cross‐sectionally and longitudinally. Aims We aimed to uncover monitoring‐based cognitive control processes and often‐overlooked strategy use in academic tasks requiring a balancing of speed and accuracy ...

The star formation history of early-type galaxies in the fornax cluster [PDF]
, 1998 We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

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.

Galaxy mergers and disk angular momentum evolution: stellar halos as a critical test
The Open Journal of AstrophysicsWe investigate the role of hierarchical assembly in the angular momentum (AM) evolution of galaxies using a sample of 471 Milky Way-mass galaxies from the TNG-50 simulation. While galaxy orientation is often attributed to tidal torques and the cooling of

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping
Computer Graphics Forum, EarlyView.Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]
, 2006 In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Planetary nebulae as kinematic tracers of galaxy stellar halos
, 2016 The kinematic and dynamical properties of galaxy stellar halos are difficult to measure because of the faint surface brightness that characterizes these regions.

Figuring Out Gas and Galaxies in Enzo (FOGGIE). VII. The (Dis)assembly of Stellar Halos
The Astrophysical JournalOver the next decade, the astronomical community will be commissioning multiple wide-field observatories well suited for studying stellar halos in both integrated light and resolved stars. In preparation for this, we use five high-resolution cosmological

Stellar halos around Local Group galaxies [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractThe Local Group is now home to 102 known galaxies and candidates, with many new faint galaxies continuing to be discovered. The total stellar mass range spanned by this population covers a factor of close to a billion, from the faintest systems with stellar masses of order a few thousand to the Milky Way and Andromeda, with stellar masses of ...
