Unusually Large Fluctuations in the Statistics of Galaxy Formation at High Redshift
We show that various milestones of high-redshift galaxy formation, such as the formation of the first stars or the complete reionization of the intergalactic medium, occurred at different times in different regions of the universe. The predicted spread in redshift, caused by large-scale fluctuations in the number density of galaxies, is at least an order of magnitude larger than previous expect...
متن کاملNear-Infrared Observations of Powerful High-Redshift Radio Galaxies: 4C 40.36 and 4C 39.37 1,2
We present near-infrared imaging and spectroscopic observations of two FR II high-redshift radio galaxies (HzRGs), 4C 40.36 (z = 2.3) and 4C 39.37 (z = 3.2), obtained with the Hubble, Keck, and Hale Telescopes. High resolution images were taken with filters both in and out of strong emission lines, and together with the spectroscopic data, the properties of the line and continuum emissions were...
متن کاملUnusually large prostatic utricle cyst.
Prostatic utricle cyst is one of the uncommon conditions and only a few cases have been reported. We present a case of unusually large prostatic utricle cyst in a 13- year- old male. He presented with burning urination and post-void dribbling of urine. A cystic mass was felt on digital per rectal examination. Ultrasound pelvis revealed a well-defined midline cystic mass posterior to the urinary...
متن کاملWide-field mid-infrared and millimetre imaging of the high-redshift radio galaxy, 4C 41.17
We present deep 350and 1200-μm imaging of the region around 4C 41.17 – one of the mostdistant (z = 3.792) and luminous known radio galaxies – obtained with the Submillimeter High Angular Resolution Camera (SHARC-II) and the Max Planck Millimeter Bolometer Array (MAMBO). The radio galaxy is robustly detected at 350 and 1200 μm, as are two nearby 850μm-selected galaxies; a third 850-μm source is ...
متن کاملUnusually large sialolith of submandibular gland
Introduction: Pathologically sialolithiasis is a disease which results in the obstruction of a salivary gland by a sialolith. Sialolith is generally seen in small size and their sizes range from 1 mm to 1 cm. Large salivary gland calculi are infrequent and defined as the size of 1.5 cm or larger. Only a few cases of large sialolith of the submandibular glands have been reported in literature. I...
