Diverse nuclear star-forming activities in the heart of NGC 253 resolved with ten-pc scale ALMA images
Ryo Ando, Kouichiro Nakanishi, Kotaro Kohno +13
We present an 8 pc x 5 pc resolution view of the central ~ 200 pc region of the nearby starburst galaxy NGC 253, based on ALMA Band 7 (λ ~ 0.85 mm or ν ~ 350 GHz) observations cove…
FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) I: Project Overview and Initial Results
Tomofumi Umemoto, Tetsuhiro Minamidani, Nario Kuno +41
The FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) project is one of the legacy projects using the new multi-beam FOREST receiver installed…
Chirally cosmetic surgeries and Casson invariants
Kazuhiro Ichihara, Tetsuya Ito, Toshio Saito
We study chirally cosmetic surgeries, that is, a pair of Dehn surgeries on a knot producing homeomorphic 3-manifolds with opposite orientations. Several constraints on knots and su…
Topological conjugacy of topological Markov shifts and Ruelle algebras
Kengo Matsumoto
We will characterize topologically conjugate two-sided topological Markov shifts in terms of the associated asymptotic Ruelle -algebras …
Discovery of a distant molecular cloud in the extreme outer Galaxy with the Nobeyama 45-m telescope
Mitsuhiro Matsuo, Hiroyuki Nakanishi, Tetsuhiro Minamidani +10
We report the discovery of the molecular cloud whose kinematic distance is the largest in the Galaxy at the present moment, named G213.0420.003, at 213.042 and $b…
Asymptotic continuous orbit equivalence of Smale spaces and Ruelle algebras
Kengo Matsumoto
In the first part of the paper, we introduce notions of asymptotic continuous orbit equivalence and asymptotic conjugacy in Smale spaces and characterize them in terms of their asy…
