RR Lyrae stars in the GCVS observed by the Qatar Exoplanet Survey [PDF]

open access: yes, 2015
This publication was made possible by NPRP grant # X-019-1-006 from the Qatar National Research Fund (a member of Qatar Foundation). AAF is grateful to DGAPA-UNAM for grant number IN104612.We used the light curve archive of the Qatar Exoplanet Survey to ...

Where Are the First Stars Now? [PDF]

open access: yes, 2006
We use high-resolution simulations to show that the current standard paradigm for the growth of structure in the Universe predicts the formation of a galaxy like our own to differ substantially from the classic ELS and Searle/Zinn pictures. On scales larger than the Local Group, the earliest star formation was extremely inhomogeneous, suggesting that ...

Constraining reionization morphology and source properties with 21 cm galaxy cross-correlation surveys

open access: yesAstronomy & Astrophysics
Cross-correlations between 21 cm observations and galaxy surveys provide a powerful probe of reionization by providing robustness against foreground contamination while linking ionization morphology to galaxies. We quantified the constraining power of 21

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

open access: yesPediatric 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 ...

PRISMS: U37126, a very blue ISM-naked starburst at z = 10.255 with a nearly 100% Lyman continuum escape fraction

open access: yesAstronomy & Astrophysics
We present very deep (≈11 hours on-source) JWST/MIRI low-resolution spectroscopy of the rest-frame optical emission of U37126, a UV-bright (MUV ≃ −20) mildly lensed (μ ≃ 2.2) galaxy at z = 10.255.

“We Cannot Talk as a Family”: Complexities of Survivorship Communication Among Hispanic/Latino Young Adult Survivors of Childhood Cancer, Parents, and Clinicians

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Young adult childhood cancer survivors (YA‐CCS) have an increased risk of treatment‐related health complications throughout their lives. Lifelong survivorship care is recommended, yet many YA‐CCS experience disruptions in care during pediatric‐to‐adult transitions and do not receive recommended survivorship care.

Magnetic Doppler imaging of early-type stars

open access: yes, 2010
Doppler imaging of early-type magnetic stars is the most advanced method to interpret their line profile variations. DI allows us to study directly a complex interplay between chemical spots, magnetic fields, and the mass loss.

The First Stars: Formation of Binaries and Small Multiples [PDF]

open access: yes, 2010
We investigate the formation of metal-free, Population III (Pop III), stars within a minihalo at z similar or equal to 20, starting from cosmological initial conditions. We follow the collapsing gas in the center of the minihalo up to number densities of

Weighing gas-rich starless halos: Dark matter parameter inference based on gas distributions

open access: yesAstronomy & Astrophysics
Context. Reionization-limited H I clouds (RELHICs) are starless dark matter halos that retain a significant neutral hydrogen (H I) reservoir. The gas resides in near hydrostatic equilibrium within the dark matter potential and in thermal equilibrium with

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...
