Although the signal is too weak to detect in individual galaxies, we analyze the feasibility of its statistical detection via stacking CMB data on many galaxies for which the spin orientation can be estimated spectroscopically. We use an “optimistic” model, in which fully ionized atmospheres contain the cosmic baryon fraction and spin at the halo’s circular velocity 𝑣circ, and a more realistic model, based on hydrodynamical simulations, with multiphase atmospheres spinning at a fraction of 𝑣circ. We incorporate realistic noise estimates into our analysis. Using low-redshift galaxy properties from the MaNGA spectroscopic survey (with median halo mass of 6.6×1011  𝑀⊙), and CMB data quality from Planck, we find that a 3⁢𝜎 detection would require a few×104 galaxies, even in the optimistic model. This is too high for current surveys, but upcoming higher-angular resolution CMB experiments will significantly reduce the requirements: stacking CMB data on galaxy spins in a ∼10 deg2 can rule out the optimistic models, and ≈350  deg2 will suffice for a 3⁢𝜎 detection with ACT. As a proof-of-concept, we stacked Planck data on the position of ≈2,000 MaNGA galaxies, aligned with the galaxies’ projected spin, and scaled to their halos’ angular size. We rule out average temperature dipoles larger than ≈1.9  𝜇⁢K around field spiral galaxies."}],"publication_status":"published","intvolume":"       101","date_published":"2020-04-10T00:00:00Z","article_type":"original","issue":"8","language":[{"iso":"eng"}],"status":"public","day":"10","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.1909.04690","open_access":"1"}],"date_created":"2024-09-05T12:37:26Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","author":[{"full_name":"Matilla, José Manuel Zorrilla","first_name":"José Manuel Zorrilla","last_name":"Matilla"},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"}],"type":"journal_article","publisher":"American Physical Society","article_number":"083016","oa_version":"Preprint","date_updated":"2024-09-19T12:26:58Z","citation":{"mla":"Matilla, José Manuel Zorrilla, and Zoltán Haiman. “Probing Gaseous Galactic Halos through the Rotational Kinematic Sunyaev-Zeldovich Effect.” <i>Physical Review D</i>, vol. 101, no. 8, 083016, American Physical Society, 2020, doi:<a href=\"https://doi.org/10.1103/physrevd.101.083016\">10.1103/physrevd.101.083016</a>.","chicago":"Matilla, José Manuel Zorrilla, and Zoltán Haiman. “Probing Gaseous Galactic Halos through the Rotational Kinematic Sunyaev-Zeldovich Effect.” <i>Physical Review D</i>.
