Abstract We present Galaxy Line Emission & Absorption Modeling ( gleam ), a Python tool for fitting Gaussian models to emission and absorption lines in large samples of 1D extragalactic spectra. is tailored work well batch mode without much human interaction. With , users can uniformly process variety spectra, including galaxies active galactic nuclei, wide range instrument setups signal-to...

September 2016—It’s the kind of health promotion advice one might pick up casually over lunch with friends, in a quick Google search, or during a visit to the hairdresser. Take megadoses of an over-the-counter vitamin called biotin—a common supplement in multivitamin compounds—and watch your skin improve and your hair and nails thicken and gleam. In recent years, online social networks and heal...

The low frequency radio source GLEAM-X J162759.5−523504.3 emits pulsed coherent polarized emission like that of pulsars. Yet its period 18.18 min (1091 s) is hundreds times longer than those confirmed pulsars, and if it a neutron star mean radiated power exceeds the upper limit on spin-down by more an order magnitude. This may be explained white dwarf pulsar, with moment inertia several orders ...

Abstract The nature of the long-period radio transient GLEAM-X J162759.5−523504.3 (hereafter J1627) is discussed. We try to understand both its emission and pulsation in neutron star scenario as an alternative white dwarf model. think that (1) from point view, J1627 can be a radio-loud magnetar; (2) rotational evolution unlikely isolated (3) 1091 s period precession period; (4) may magnetar spu...
