An asymmetric explosion as the origin of spectral evolution diversity in type Ia supernovae [PDF]

, 2010
Type Ia Supernovae (SNe Ia) form an observationally uniform class of stellar explosions, in that more luminous objects have smaller decline-rates. This one-parameter behavior allows SNe Ia to be calibrated as cosmological `standard candles', and led to ...

Changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years and linkages to environmental factors

Journal of Fish Biology, EarlyView.
Abstract Quantifying the potential effects of climate change on juvenile salmonid body length at a large spatiotemporal scale is challenging given the multitude of biological processes and methodological constraints. In the present work, we analysed potential changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years in the ...

Stellar mass loss and the Intra-Cluster Medium in Galactic globular clusters: a deep radio survey for HI and OH

, 2005
We present the results of a survey, the deepest to date, for HI emission at 21 cm and OH emission at 18 cm (lines at 1612, 1665, 1667 and 1720 MHz) in the direction towards the Galactic globular clusters M 15, M 2, NGC 6934, NGC 7006 and Pal 13.

Vernalization regulatory network identifies potential novel functions for genes in the HvVRN2 locus

New Phytologist, EarlyView.
Summary Flowering is controlled by environmental and genetic factors. Vernalization requirement in barley (Hordeum vulgare L.) is determined by the allele in HvVRN1 and the presence of locus HvVRN2, which consists of two zinc‐finger and CONSTANS‐like domains (ZCCT) genes: HvVRN2a and HvVRN2b.

Determination of the Hubble Constant Using a Two-Parameter Luminosity Correction for Type Ia Supernovae

, 1999
In this paper, we make a comprehensive determination of the Hubble constant $H_0$ by using two parameters - the B-V color and the rate of decline $\Delta m_{15}$ - to simultaneously standardize the luminosities of all nearby Cepheid-calibrated type Ia ...

VLT/UVES Spectroscopy of Individual Stars in Three Globular Clusters in the Fornax Dwarf Spheroidal Galaxy [PDF]

, 2006
We present a high resolution (R ~ 43000) abundance analysis of a total of nine stars in three of the five globular clusters associated with the nearby Fornax dwarf spheroidal galaxy.

Creative Discretion on the Frontline of Public Services: A Longitudinal Qualitative Digital Diary and Interview Study

Public Administration, EarlyView.
ABSTRACT “Creative discretion”—defined as street‐level bureaucrats' use of their discretion to generate novel and useful ideas for customizing services to meet the needs of service users, superiors, and themselves—is vital as governments shift from traditional public management to a more user‐centered approach, emphasizing responsiveness over ...

Fabry-Perot Measurements of the Dynamics of Globular Cluster Cores: M15 (NGC~7078)

, 1994
We report the first use of the Rutgers Imaging Fabry-Perot Spectrophotometer to study the dynamics of the cores of globular clusters. We have obtained velocities for cluster stars by tuning the Fabry-Perot to take a series of narrow-band images at ...
