Intermediate-band Surface Photometry of the Edge-on Galaxy: NGC 4565
Hong Wu, Dave Burstein, Zugan Deng
We present a deep, 42.79 hr image of the nearby, edge-on galaxy NGC 4565 in the Beijing-Arizona-Taipei-Connecticut (BATC) 6660A band using the large-format CCD system on the 0.6m S…
Synthetic Color-Magnitude Diagrams for omega Centauri and Other Massive Globular Clusters with Multiple Populations
Chang H. Ree, Suk-Jin Yoon, Soo-Chang Rey +1
We have constructed synthetic color-magnitude diagrams (CMDs) for omega Cen and other massive globular clusters with apparently peculiar CMD morphology. Our population models, whic…
Omega Centauri as a Disrupted Dwarf Galaxy: Evidence from Multiple Stellar Populations
Young-Wook Lee, Soo-Chang Rey, Chang H. Ree +4
Our recent CCD photometry (Lee et al. 1999) has shown, for the first time, that omega Cen has several distinct stellar populations, which is reminiscent of the Sagittarius dwarf ga…
Wide-field High-precision CCD Photometry of omega Centauri and Its RR Lyrae Stars
Soo-Chang Rey, Jong-Myung Joo, Young-Jong Sohn +3
We present wide-field and high-precision BV and Ca & Stromgren by photometry of omega Centauri and its RR Lyrae stars, which represents one of the most extensive photometric survey…
The Kramers-Heisenberg Formula and the Gunn-Peterson Trough from the First Objects in the Universe
Kiehunn Bach, Hee-Won Lee
Recent cosmological observations indicate that the reionized universe may have started at around z=6, where a significant suppression around Ly alpha has been observed from the neu…
A New Distance Estimator and Spatial Distribution of GRBS Observed by BATSE
Heon-Young Chang, Suk-Jin Yoon, Chul-Sung Choi
We propose a redshift estimator for the long () gamma-ray bursts (GRBs) observed by the BATSE. It is based on an empirical relation between the redshift and the power-…
CCD Photometry of the Classic Second Parameter Globular Clusters M3 and M13
Soo-Chang Rey, Suk-Jin Yoon, Young-Wook Lee +2
We present high-precision V, B-V color-magnitude diagrams (CMDs) for the classic second parameter globular clusters M3 and M13 from wide-field deep CCD photometry. The data for the…
Compact Objects and Accretion Disks
Roger Blandford, Eric Agol, Avery Broderick +3
Recent developments in the spectropolarimetric study of compact objects, specifically black holes (stellar and massive) and neutron stars are reviewed. The lectures are organized a…
Spectrophotometric Evolution of Old Stellar Systems
Hyun-chul Lee
Theoretical integrated spectrophotometric quantities, such as spectral line indices in the Lick system (Hbeta, Mg2, Mg b, Fe5270, Fe5335), broadband color indices (in the UBVRIHK a…
Towards Better Age Estimates for Stellar Populations: The Y^2 Isochrones for Solar Mixture
S. Yi, P. Demarque, Y. -C. Kim +4
We have constructed a new set of isochrones, called the Y^2 Isochrones, that represent an update of the Revised Yale Isochrones (RYI), using improved opacities and equations of sta…
Raman Scattered He II Line in the Planetary Nebula M2-9 and the Symbiotic Stars RR Telescopii and He 2-106
Hee-Won Lee, Yong-Woo Kang, Yong-Ik Byun
In this Letter, we report the detection of an emission feature around 6545 Åin the spectra of the bipolar planetary nebula M2-9 and the symbiotic stars RR Telescopii and He 2-106 a…
