Limb-darkening measurements for a cool red giant in microlensing event OGLE 2004-BLG-482
M. Zub, A. Cassan, D. Heyrovsky +47
Aims: We present a detailed analysis of OGLE 2004-BLG-482, a relatively high-magnification single-lens microlensing event which exhibits clear extended-source effects. These events…
Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events
C. Han, K. -H. Hwang, D. Kim +87
To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of len…
Masses and Orbital Constraints for the OGLE-2006-BLG-109Lb,c Jupiter/Saturn Analog Planetary System
D. P. Bennett, S. H. Rhie, S. Nikolaev +70
We present a new analysis of the Jupiter+Saturn analog system, OGLE-2006-BLG-109Lb,c, which was the first double planet system discovered with the gravitational microlensing method…
Reverberation Mapping Results from MDM Observatory
Kelly D. Denney, B. M. Peterson, R. W. Pogge +6
We present results from a multi-month reverberation mapping campaign undertaken primarily at MDM Observatory with supporting observations from around the world. We measure broad li…
Diverse Broad Line Region Kinematic Signatures From Reverberation Mapping
K. D. Denney, B. M. Peterson, R. W. Pogge +40
A detailed analysis of the data from a high sampling rate, multi-month reverberation mapping campaign, undertaken primarily at MDM Observatory with supporting observations from tel…
Extreme Magnification Microlensing Event OGLE-2008-BLG-279: Strong Limits on Planetary Companions to the Lens Star
J. C. Yee, A. Udalski, T. Sumi +14
We analyze the extreme high-magnification microlensing event OGLE-2008-BLG-279, which peaked at a maximum magnification of A ~ 1600 on 30 May 2008. The peak of this event exhibits…
Mass measurement of a single unseen star and planetary detection efficiency for OGLE 2007-BLG-050
V. Batista, Subo Dong, A. Gould +93
We analyze OGLE-2007-BLG-050, a high magnification microlensing event (A ~ 432) whose peak occurred on 2 May, 2007, with pronounced finite-source and parallax effects. We compute p…
XMM-Newton observations of SDSS J143030.22001115.1: an unusually flat spectrum AGN
S. Mathur, E. C. Golowacz, R. Williams +3
We present XMM observations of the AGN SDSS 1430-0011. The low S/N spectrum of this source obtained in a snap shot Chandra observation showed an unusually flat continuum. With the…
The Extreme Microlensing Event OGLE-2007-BLG-224: Terrestrial Parallax Observation of a Thick-Disk Brown Dwarf
A. Gould, A. Udalski, B. Monard +10
Parallax is the most fundamental technique to measure distances to astronomical objects. Although terrestrial parallax was pioneered over 2000 years ago by Hipparchus (ca. 140 BCE)…
Asteroid Distributions in the Ecliptic
Erin L. Ryan, Charles E. Woodward, Andrea Dipaolo +7
We present analysis of the asteroid surface density distribution of main belt asteroids (mean perihelion AU) in five ecliptic latitude fields, $-17 \gtsimeq β(\degr…
The Nuclear Outflows and Feedback in the Seyfert 2 Galaxy Markarian 573
K. Schlesinger, Richard W. Pogge, Paul Martini +2
We present a study of outflow and feedback in the well-known Seyfert 2 galaxy Markarian 573 using high angular resolution long-slit spectrophotometry obtained with the Hubble Space…
