We present azimuthally-averaged spectral energy distributions (SEDs) from FUV to FIR, as a function of radius, for the galaxies included in the SINGS sample. The radial changes in these SEDs are interpreted in terms of variations of the relative contribution of stars (of different ages), dust and gas.

We present the first automated fitting method for the quantitative spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE stellar atmosphere code fastwind from Puls et al. (2005, A&A, 435, 669) with the genetic algorithm based optimization routine pikaia from Charbonneau (1995, ApJS, 101, 309), allowing for a

Aims:We present an analysis of high resolution spectra in the J band of five ultra cool dwarfs from M6 to L0. Methods: We make use of a new ab initio water vapour line list and existing line lists of FeH and CrH for modelling the observations. Results: We find a good fit for the Mn I 12 899.76 Å line. This feature is one of the few for which we

NASA's OSIRIS-REx mission is currently on its way to the asteroid (101955) Bennu. Bennu is a primitive asteroid, characterized by a dark surface composed mainly of carbon compounds, organic, and silicates altered by the presence of water. In addition, due to its proximity to the Earth, is classified as a potentially dangerous asteroid (PHA). Among

The far-infrared (FIR) properties of Quasi-Stellar Objects (QSOs) is important in connecting the Starburst (SB) and Active Galactic Nucleus (AGN) activities. Therefore, we constructed a 24 μ m selected QSO sample to study their FIR behavior. All sources were spectroscopically identified from MMT or the Sloan Digital Sky Survey (SDSS) as broadline

Transient radio emission from X-ray binaries is associated with synchrotron emission from collimated jets that escape the system, and accreting millisecond X-ray pulsars (AMXPs) are no exception. Although jets from black hole X-ray binaries are well-studied, those from neutron star systems appear much fainter, for reasons yet uncertain. Jets are
