Clearly the redshift limit is extremely distant! ===================================== From: djtost@juno.com To: bas@lowell.edu Cc: bwilson2@ix.netcom.com Date: Sun, 30 May 1999 12:16:57 -0500 Subject: High Redshift Quasars Brian, I received your inquiry about some of the high redshift objects I have been viewing through Barbara Wilson. We just got back from a wonderful Texas Star Party, with over 52 hours of clear skies! For several years I have looked through the literature before TSP to find some high redshift objects visible in amateur instruments. In 1997 we viewed B1422+231, a gravitationally-lensed system with z=3.62. It is m16.5 (red), with the radio image revealing 4 objects within 1.3 arcseconds. The ref. is MNRAS (1992) 259, Short Comm., 1p-4p. There is another ref. to it in ApJ Nov. 10, 1998 (Yoshi & Kawara), alluded to in Sky & Tel. April 1999 News Notes, p. 23. The J2000 Coord. are: 14h 24m 38.1s, +22d 56' 00". This spring I found APM 08279+5255, a z=3.87 quasar in Lynx, m15.5 at J2000 08h 31m 41.57s, +52d 45' 17.7". These were both easily viewed through my 25-inch Tectron. There are a few more Quasars with z> 3.0, but these are the highest redshift objects viewed thus far. Dave Tosteson
