CDROM/AJ/V105/P0035 Blue Galaxy Survey (Coziol+ 1993) ================================================================================ The Montreal Blue Galaxy Survey. I. First List of Ultraviolet-Bright Candidates Roger Coziol, Serge Demers, Miriam Pena, Silvia Torres-Peimbert, G. Fontaine, F. Wesemael, & R. Lamontagne <1993, AJ, 105, 35> =1993AJ....105...35C ================================================================================ Abstract: We describe and present the first results of a UV-bright galaxy survey using the Montreal-Cambridge-Tololo (MCT) plate collection. Visual inspection of 57 CTIO Curtis Schmidt plates, covering more than 1300 sq. deg., has resulted in the identification of 95 UV-bright galaxies brighter than B = 15.5. Even though 80% of these objects are IRAS sources, barely 20% have their nature already established. The initial result of our survey shows that the bulk of our UV-bright candidates are narrow emission-line galaxies commonly known as starburst or HII galaxies. The fraction of AGNs found is somewhat less than 10%, but comparable to what has been found by the Markarian survey. We expect to find approximately 500 UV-bright galaxies in the 7000 sq. deg. of the MCT Survey with b < -40 deg. As we go further south, a large number of bright new objects will be discovered.

Uncertainties for the coordinates are on the order or arcseconds. Formal uncertainties for B is +/- 1 mag and +/- 1.4 mag for U-B. -------------------------------------------------------------------------------- Byte-by-byte Description of file: table1.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1-10 A10 --- MBG Montreal Blue Galaxy (MBG) name 11-13 F3.0 h RAh Hour of RA (1950) 14-16 F3.0 min RAm Min of RA 17-21 F6.1 s RAs Sec of RA 22 1X --- --- Blank 23 A1 --- DE- Sign of Dec.

MBG00163-1039 is a known interacting galaxy called ARP 256. MBG00276-1013 is a Markarian galaxy considered by Denisyuk & Lipovetsky (1984) to have a spectrum somewhat similar to an HII region. MBG00439-1342 is a shell galaxy. MBG00461-1259 is a known blue compact Markarian galaxy. MBG01234-4143 was found by Fairall (1988) to be a non-Seyfert emission-line galaxy with an offset nucleus. MBG01329-4141 is NGC 625, its HII-like nucleus is not highly excited. Its optical spectrum was obtained by Phillips et al. (1983). MBG01334-3455 is a HII region-like galaxy (Kirhakos & Steiner 1990). MBG01357-4047 has, according to the same authors, a spectrum btween a Sy2 and a HII galaxy. MBG01497-3639 was found by Allen et al. (1991) to be a starburst galaxy. MBG01593-3830 in ESO 298-G001, a blue galaxy. Bergvall & Olofsson (1986) give V = 15.72, B-V = 0.45, and U-B = -0.30. MBG02280-0426 has been found in the Kiso survey by Takase & Miyauchi-Isobe (1988), where it is called KUG 0228-044. MBG02490-2709 is a member of the interacting galaxies AM 0248-270. MBG03174-1935 is NGC 1300, a bright HII galaxy. MBG03183-1853 is catalogued by Lipovetsky et al. (1988) as a Seyfert galaxy. MBG03260-1735 is an active dwarf galaxy (Thronson & Telesco 1986). MBG03273-1756 is an Haro object, a blue compact interacting galaxy. MBG03317-2026 is NGC 1362, a blue galaxy without emission lines. MBG03352-2439 is a known nearby starburst radiogalaxy (Devereux 1989). MBG03462-2502 has V = 15.12, B-V = 0.31, U-B = -0.20 (Bergvall & Olofsson 1986). MBG04046-2118 is NGC 1518, which seems to be a normal irregular galaxy. MBG22342-2228 is an emission-line galaxy observed by Moody & Kirshner (1988) -------------------------------------------------------------------------------- References to the Notes: -------------------------------------------------------------------------------- Allen, D.
