Galaxy transformation across the cosmic web: The influence zone of filaments
Astronomy & AstrophysicsContext. The matter distribution in the Universe exhibits a rich variety of structures, and they form the so-called cosmic web. These structures arise from the anisotropic gravitational collapse of primordial density fluctuations and define the pathways ...

Quasars and large scale structure of the universe [PDF]
, 2008 The majority of bright distant quasars $(z {}^{>}_{\sim} 1)$ may form in massive mergers appearing in compact galaxy groups in/and young clusters. The expected tests are (i) large correlation signal for medium-$z$ QSOs $(1 < z < 2)$ and (ii) direct search for quasar groups (QGs) indicating positions of distant pre-superclusters which later ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Large scale structure in the Durham/UKST galaxy Redshift survey [PDF]
, 1996 The initial results from the Durham/UKST Galaxy Redshift Survey are presented here. Using this redshift survey the luminosity, clustering and dynamical properties of galaxies in the Universe are investigated.

Unclustered tracers remain unclustered
Astronomy & AstrophysicsConstraining primordial non-Gaussianities (PNGs) is one of the main goals of new-generation large-scale galaxy surveys. It had been proposed that unclustered tracers (with bias b1 = 0) could be optimal for PNG studies, and that these could be found by ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

Cosmology with inhomogeneous magnetic fields [PDF]
, 2007 We review spacetime dynamics in the presence of large-scale electromagnetic fields and then consider the effects of the magnetic component on perturbations to a spatially homogeneous and isotropic universe.

Mapping the Large-Scale Structure of the Universe
Science, 2005 In a large scale view of the universe, galaxies are the basic unit of structure. A typical bright galaxy may contain 100 billion stars and span tens of thousands of light years, but the empty expanses between the galaxies are much larger still. Galaxies are not randomly distributed in space, but instead reside in groups and clusters, which are ...
