The Gas Content and Kinematics of Nearby Blue Compact Galaxies: Implications for Studies at Intermediate and High Redshift
We present Arecibo 21 cm spectroscopy, Keck HIRES Hb spectroscopy, and WIYN R-band imaging of 11 nearby blue compact galaxies with e†ective B-band surface brightnesses of SBe \ 19.4È21.2 mag arcsec~2 and e†ective radii of kpc. This sample was selected to test the reliability of mass Reff \ 0.6È1.9 estimates derived using optical emission line widths, particularly for the blue compact star-formi...
متن کاملThe Nature of Nearby Counterparts to Intermediate-Redshift Luminous Compact Blue Galaxies. III. Interferometric Observations of Neutral Atomic and Molecular Gas
We present the results of a Very Large Array (VLA) and Owens Valley Radio Observatory Millimeter Wavelength Array (OVRO–MMA) follow-up to our single-dish surveys of the neutral atomic and molecular gas in a sample of nearby Luminous Compact Blue Galaxies (LCBGs). These luminous, blue, high surface brightness, starbursting galaxies were selected using criteria similar to that used to define LCBG...
متن کاملPossible Local Spiral Counterparts to Compact Blue Galaxies at Intermediate Redshift
We identify nearby disk galaxies with optical structural parameters similar to those of intermediateredshift compact blue galaxies. By comparing H I and optical emission-line widths, we show that the optical widths substantially underestimate the true kinematic widths of the local galaxies. By analogy, optical emission-line widths may underrepresent the masses of intermediate-z compact objects....

We present the results of a single-dish beam-matched survey of the three lowest rotational transitions of CO in a sample of 20 local (D 70 Mpc) Luminous Compact Blue Galaxies (LCBGs). These ∼L ⋆ , blue, high surface brightness, starbursting galaxies were selected with the same criteria used to define LCBGs at higher redshifts. Our detection rate was 70%, with those galaxies having L B < 7 × 10 ...
متن کاملStellar Populations Found in the Central kpc of Four Luminous Compact Blue Galaxies at Intermediate
We investigate the star formation history of the central regions of four Luminous Compact Blue Galaxies (LCBGs) at intermediate redshift using evolutionary population synthesis techniques. LCBGs are blue (B−V ≤ 0.6), compact (μB ≤ 21.0 mag arcsec−2) galaxies with absolute magnitudes MB brighter than -17.5. The LCBGs analyzed here are located at 0.436 ≤ z ≤ 0.525. They are among the most luminou...
