Off-Axis Energy Variability of AGNs: a New Paradigm for Broad-Line- and Continuum-Emitting Regions
accretion, accretion disks—black hole physics—galaxies: active— galaxies: Seyfert — polarization — quasars: emission lines
2011/10/17
The general picture of how thermal AGNs work has become clearer in recent years but major observational puzzles threaten to undermine this picture. These puzzles include AGNs with extremely asymmetric...
Orbital Angular Momentum in Noncollinear Second Harmonic Generation by off-axis vortex beams
Harmonic generation and mixing Optical Vortices Orbital Angular Momentum
2011/8/31
We experimentally study the behavior of orbital angular momentum (OAM) of light in a noncollinear second harmonic generation (SHG) process. The experiment is performed by using a type I BBO crystal un...
Proto-Model of an Infrared Wide-Field Off-Axis Telescope
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/24
We develop a proto-model of an off-axis reflective telescope for infrared wide-field observations based on the design of Schwarzschild-Chang type telescope. With only two mirrors, this design achieves...
Water vapor δ2H and δ18O measurements using off-axis integrated cavity output spectroscopy
Water vapor δ2H δ18O measurements cavity output spectroscopy
2010/2/8
We present a detailed assessment of a commercially available water vapor isotope analyzer (WVIA, Los Gatos Research, Inc.) for simultaneous in-situ measurements of δ2H and δ18O in water vapor. This me...

A compact and stable eddy covariance set-up for methane measurements using off-axis integrated cavity output spectroscopy
compact stable eddy covariance set-up methane measurements off-axis spectroscopy
2008/10/27
A Fast Methane Analyzer (FMA) is assessed for its applicability in a closed path eddy covariance field set-up in a peat meadow. The FMA uses off-axis integrated cavity output spectroscopy combined wit...
