Community-based disaster preparedness is an important component of disaster management. Knowledge of interventions that communities utilize in response to hazards is important to develop local-level capacity and increase ...

We have conducted an H I 21 cm emission-line survey of six loose groups of galaxies chosen to be analogs to the Local Group. The survey was conducted using the Parkes multibeam instrument and the Australia Telescope Compact ...

A clear prediction of the cold dark matter (CDM) model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation curves of spiral galaxies, challenging ...

Proton inelastic scattering off a neutron halo nucleus, ¹¹Li, has been studied in inverse kinematics at the IRIS facility at TRIUMF. The aim was to establish a soft dipole resonance and to obtain its dipole ...

The X-ray spectra of many active galactic nuclei exhibit a “soft excess” below 1 keV, whose physical origin remains unclear. Diverse models have been suggested to account for it, including ionized reflection ...

An experiment, suitable for an introductory laboratory course, is described in which a relatively common household item--the microwave oven--is used to do a heat experiment verifying the conservation of energy principle.

The structures of ([eta superscript 5]-cyclopentadienyl)[(1,2,3,4,4a,10a-[eta superscript 6])-dibenzo[b,e][1,4]dioxin]iron(II) hexafluorophosphate (1), [Fe(C[subscript 5]H[subscript 5])(C[subscript 12]H[subscript 8]O[subscript ...

We present a high density disc reflection spectral analysis of a sample of 17 Seyfert 1 galaxies to study the inner disc densities at different black hole mass scales and accretion rates. All the available XMM– ...
