ZuHone (NASA/GSFC) on behalf of the ASTRO-H Science Working Group Abstract The next generation X-ray observatory ASTRO-H will open up a new dimension in the study of galaxy clusters by achieving for the first time the spectral resolution required to measure velocities of the intracluster plasma, and extending at the same time the spectral coverage to energies well beyond 10 keV. This white paper provides an overview of the capabilities of ASTRO-H for exploring gas motions in galaxy clusters including their cosmological implications, the physics of AGN feedback, dynamics of cluster mergers as well as associated high-energy processes, chemical enrichment of the intracluster medium, and the nature of missing baryons and unidentified dark matter. arXiv:1412.1176v1 [astro-ph.HE] 3 Dec 2014 1Also at Institute of Astronomy, University of Cambridge 1 Complete list of the ASTRO-H Science Working Group Tadayuki Takahashia, Kazuhisa Mitsudaa, Richard Kelleyb, Felix Aharonianc, Hiroki Akamatsud, Fumie Akimotoe, Steve Allenf, Naohisa Anabukig, Lorella Angelinib, Keith Arnaudh, Marc Audardi, Hisamitsu Awakij, Aya Bambak, Marshall Bautzl, Roger Blandfordf, Laura Brennemanb, Greg Brownm, Edward Cackettn, Maria Chernyakovac, Meng Chiaob, Paolo Coppio, Elisa Costantinid, Jelle de Plaad, Jan-Willem den Herderd, Chris Donep, Tadayasu Dotania, Ken Ebisawaa, Megan Eckartb, Teruaki Enotoq, Yuichiro Ezoer, Andrew Fabiann, Carlo Ferrignoi, Adam Fosters, Ryuichi Fujimotot, Yasushi Fukazawau, Stefan Funkf, Akihiro Furuzawae, Massimiliano Galeazziv, Luigi Gallow, Poshak Gandhip, Matteo Guainazzix, Yoshito Habay, Kenji Hamaguchih, Isamu Hatsukadez, Takayuki Hayashia, Katsuhiro Hayashia, Kiyoshi Hayashidag, Junko Hiragaaa, Ann Hornschemeierb, Akio Hoshinoab, John Hughesac, Una Hwangad, Ryo Iizukaa, Yoshiyuki Inouea, Hajime Inouea, Kazunori Ishibashie, Manabu Ishidaa, Kumi Ishikawaq, Yoshitaka Ishisakir, Masayuki Itoae, Naoko Iyomotoaf, Jelle Kaastrad, Timothy Kallmanb, Tuneyoshi Kamaef, Jun Kataokaag, Satoru Katsudaa, Junichiro Katsutau, Madoka Kawaharadaa, Nobuyuki Kawaiah, Dmitry Khangulyana, Caroline Kilbourneb, Masashi Kimuraai, Shunji Kitamotoab, Tetsu Kitayamaaj, Takayoshi Kohmuraak, Motohide Kokubuna, Saori Konamir, Katsuji Koyamaal, Hans Krimmb, Aya Kubotaam, Hideyo Kuniedae, Stephanie LaMassao, Philippe Laurentan, Franc¸ois Lebrunan, Maurice Leuteneggerb, Olivier Limousinan, Michael Loewensteinb, Knox Longao, David Lumbap, Grzegorz Madejskif, Yoshitomo Maedaa, Kazuo Makishimaaa, Maxim Markevitchb, Hironori Matsumotoe, Kyoko Matsushitaaq, Dan McCammonar, Brian McNamaraas, Jon Millerat, Eric Millerl, Shin Mineshigeau, Ikuyuki Mitsuishie, Takuya Miyazawae, Tsunefumi Mizunou, Koji Moriz, Hideyuki Morie, Koji Mukaib, Hiroshi Murakamiav, Toshio Murakamit, Richard Mushotzkyh, Ryo Naginog, Takao Nakagawaa, Hiroshi Nakajimag, Takeshi Nakamoriaw, Shinya Nakashimaa, Kazuhiro Nakazawaaa, Masayoshi Nobukawaal, Hirofumi Nodaq, Masaharu Nomachiax, Steve O’ Dellay, Hirokazu Odakaa, Takaya Ohashir, Masanori Ohnou, Takashi Okajimab, Naomi Otaaz, Masanobu Ozakia, Frits Paerelsba, Stephane´ Paltanii, Arvind Parmarx, Robert Petreb, Ciro Pinton, Martin Pohli, F.
