The size of a quasar's mid-IR emission region inferred from microlensed images of Q2237+0305
J. S. B. Wyithe, E. Agol, C. J. Fluke
We use published mid-IR and V-band flux ratios for images A and B of Q2237+0305 to demonstrate that the size of the mid-IR emission region has a scale comparable to or larger than…
The Infall of Gas onto the Galactic Disk
Brad K. Gibson
Ongoing accretion of low-metallicity gas onto the disk is a natural prediction of semi-analytical Galactic chemical evolution models. This star formation fuel ameliorates the overp…
Radio astronomical polarimetry and phase-coherent matrix convolution
W. van Straten
A new phase-coherent technique for the calibration of polarimetric data is presented. Similar to the one-dimensional form of convolution, data are multiplied by the response functi…
Age Estimates for Globular Clusters in NGC 1399
Duncan A. Forbes, Michael A. Beasley, Jean P. Brodie +1
We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical NGC 1399, and compare measured line indices with current stellar p…
A reformulation of Hilbert's tenth problem through Quantum Mechanics
Tien D Kieu
Inspired by Quantum Mechanics, we reformulate Hilbert's tenth problem in the domain of integer arithmetics into either a problem involving a set of infinitely coupled differential…
The Optical Counterpart of the Accreting Millisecond Pulsar SAX J1808.4-3658 in Outburst: Constraints on the Binary Inclination
Zhongxiang Wang, Deepto Chakrabarty, Paul Roche +6
We present multiband optical/infrared photometry of V4580 Sgr, the optical counterpart of the accretion-powered millisecond pulsar SAX J1808.4-3658, taken during the 1998 X-ray out…
