Description
As part of a systematic survey for the search of high velocity gas in giant extragalactic H II regions, the authors have observed the five largest and brightest H II regions in M101. They have found two types of peculiar emission profiles: (1) a broadening of the Hα emission line at low intensity, in excess of the values expected for the typical gaussian profile and (2) a very broad component (FWZI > 3000 km s-1) for Hα + the [N II] doublet, located at NGC 5471.

    The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
    WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, saw first light in late 2022. WEAVE comprises a new 2-deg field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable 'mini' integral field units (IFUs), and a single large IFU

    The extent and power of 'maintenance mode' feedback in MaNGA AGN
    We study the ionized gas kinematics of 293 Active Galactic Nucleus (AGN) hosts as compared to that of 485 control galaxies from the MaNGA-SDSS survey using measurements of the [O III]$\lambda$5007 Å emission-line profiles, presenting flux, velocity, and W$_{80}$ maps. In 45 per cent of the AGN, a broad component was needed to fit the line profiles
