Indian Journal of Ophthalmology, 2022 A 65-year-old male with proliferative diabetic retinopathy (PDR) and non-clearing vitreous hemorrhage underwent 25G pars plana vitrectomy (PPV). A large disk of thick organized blood of 5 disk diameter (DD) size was encountered in subhyaloid space.

Chemical constraints on the formation of the Galactic thick disk
EPJ Web of Conferences, 2012 We highlight some results from our detailed abundance analysis study of 703 kinematically selected F and G dwarf stars in the solar neighbourhood. The analysis is based on spectra of high-resolution (R = 45000 to 110 000) and high signal-to-noise (S/N ...

The Astrophysical Journal, 2023 We explore reprocessing models for a sample of 17 hypervariable quasars, taken from the Sloan Digital Sky Survey Reverberation Mapping project, which all show coordinated optical luminosity hypervariability with amplitudes of factors ≳2 between 2014 and ...

The Chemical Evolution of the Galaxy: the two-infall model [PDF]
, 1996 In this paper we present a new chemical evolution model for the Galaxy which assumes two main infall episodes for the formation of halo-thick disk and thin disk, respectively. We do not try to take into account explicitly the evolution of the halo but we

Probing the distinct chemical history of the Milky Way halo and old thick disk through HESP-GOMPA survey [PDF]
EPJ Web of ConferencesRecent studies of the time-resolved Milky Way formation using asteroseismology have shown that thick disk stars could be very old (0.8 Gyr after the Big Bang, even older than the inner halo).

Radial Structure in the TW Hya Circumstellar Disk [PDF]
, 2011 We present new near-infrared interferometric data from the CHARA array and the Keck Interferometer on the circumstellar disk of the young star, TW Hya, a proposed "transition disk." We use these data, as well as previously published, spatially resolved ...

Origins of the thick disk of the galaxy as traced by metal-poor stars selected from RAVE
EPJ Web of Conferences, 2012 Models of the formation of the thick disk of the Milky Way Galaxy make specific predictions about the chemical abundance properties of the metal-weak (and oldest) stellar population in the thick disk.
