Modeling the anomaly of surface number densities of galaxies on the Galactic extinction map due to their FIR emission contamination
Toshiya Kashiwagi, Yasushi Suto, Atsushi Taruya +3
The most widely used Galactic extinction map (Schlegel, Finkbeiner, & Davis 1998, SFD) is constructed assuming that the observed FIR fluxes entirely come from the Galactic dust. Ac…
L-extendable functions and a proximity scaling algorithm for minimum cost multiflow problem
Hiroshi Hirai
In this paper, we develop a theory of new classes of discrete convex functions, called L-extendable functions and alternating L-convex functions, defined on the product of trees. W…
Design of a silica-aerogel-based cosmic dust collector for the Tanpopo mission aboard the International Space Station
Makoto Tabata, Eiichi Imai, Hajime Yano +10
We are developing a silica-aerogel-based cosmic dust collector for use in the Tanpopo experiment to be conducted on the International Space Station. The mass production of simple t…
An optimal survey geometry of weak lensing survey: minimizing super-sample covariance
Ryuichi Takahashi, Shunji Soma, Masahiro Takada +1
Upcoming wide-area weak lensing surveys are expensive both in time and cost and require an optimal survey design in order to attain maximum scientific returns from a fixed amount o…
Discovery of Four Doubly Imaged Quasar Lenses from the Sloan Digital Sky Survey
Naohisa Inada, Masamune Oguri, Cristian E. Rusu +2
We report the discovery of four doubly imaged quasar lenses. All the four systems are selected as lensed quasar candidates from the Sloan Digital Sky Survey data. We confirm their…
