High-resolution Doppler images of the spotted contact binary AE Phe
(2004-03-11)We present Doppler images of the short period (P = 0.362 d) W UMa binary AE Phe. In order to obtain the necessary S/N ratio and time resolution required to see individual star-spot features in highly rotationally broadened ... -
High-resolution imaging of stars, dust, and star formation in nuclear rings in galaxies
(Astronomical Society of the Pacific, 2001)Nuclear rings in barred spiral galaxies offer an opportunity to study starburst properties, as well as the evolution of star formation in the central regions of galaxies. To further our understanding in these areas, a large ... -
High-resolution international LOFAR observations of 4C~43.15 -- Spectral ages and injection indices in a high-z radio galaxy
(2022-02-01)It has long been known that radio sources with the steepest spectra are preferentially associated with the most distant galaxies, the α - z relation, but the reason for this relation is an open question. The spatial ... -
High-resolution mass models of dwarf galaxies from LITTLE THINGS
(2015-06)We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc. ... -
High-resolution molecular line observations of active galaxies
(2008)The study of the content, distribution and kinematics of interstellar gas is a key to understand the origin and maintenance of both starburst and nuclear (AGN) activity in galaxies. The processes involved in AGN fueling ... -
High-resolution neutron capture and transmission measurements, and the stellar neutron-capture cross section of Sr-88
(2000-11)We have made new and improved measurements of the neutron capture and total cross sections for Sr-88 at the Oak Ridge Electron Linear Accelerator (ORELA). Improvements over previous measurements include a wider incident ... -
High-resolution observations of radio sources with 0.6 < z≤ 1.0
(2006)High-resolution, high-sensitivity 8.4- and 5-GHz VLA observations and 5-GHz MERLIN observations are presented for 32 FRII radio sources with 0.6 < z≤ 1.0 from the 3CRR sample. These data conclude a long-term project in ... -
High-resolution optical spectroscopy of Praesepe white dwarfs
(2009)We present the results of a high-resolution optical spectroscopic study of nine white dwarf candidate members of Praesepe undertaken with the VLT and Ultraviolet and Visual Echelle Spectrograph. We find, contrary to a ... -
A High-Resolution Radio Continuum Study Of The Dwarf Irregular Galaxy IC 10
(2017-01-22)We present high-resolution e-MERLIN radio continuum maps of the Dwarf Irregular galaxy IC10 at 1.5GHz and 5GHz. We detect 11 compact sources at 1.5GHz, 5 of which have complementary detections at 5GHz. We classify 3 extended ... -
A High-Resolution Radio Continuum Study of the Dwarf Irregular Galaxy IC10
(2015-08-25)Dwarf galaxies are a significant contributor to the current star formation rate for the Universe as a whole, yet little is understood of what drives star formation in these low gas density environments. IC10 is a nearby ... -
High-resolution rotation curves and galaxy mass models from THINGS
(2008)We present rotation curves of 19 galaxies from The H I Nearby Galaxy Survey (THINGS). The high spatial and velocity resolution of THINGS make these the highest quality H I rotation curves available to date for a large ... -
A high-resolution spectroscopic survey of late-type stars: chromospheric activity, rotation, kinematics, and age
(2010)Aims. We present a compilation of spectroscopic data from a survey of 144 chromospherically active young stars in the solar neighborhood, which may be used to investigate different aspects of its formation and evolution ... -
High-resolution study of Np-237 fission cross section from 5 eV to 1 MeV
(American Institute of Physics (AIP), 2005)A series of measurements of Np-237 fission cross section have been performed at the CERN spallation neutron facility n_TOF which covers a wide energy range from 1 eV up to 250 MeV. A fast ionization chamber (FIC) was used ...
