The unprecedented deep UV imaging study of the jellyfish galaxy JO201 shows clear signs of extraplanar star formation activity due to a recent/ongoing gas stripping event. The integrated star formation rate from FUV flux is ∼15 M ⊙ yr -1. Similarly, also the star formation rates of individual knots derived from the extinction-corrected far-ultraviolet (FUV) emission agree with those derived from the Hα emission and range from ∼0.01 to 2.07 M ⊙ yr -1. Overall, the two emissions remarkably correlate, both in the main body and along the tentacles. As mentioned above, environmental effects, star formation and. We identify star-forming knots both in the stripped gas and in the galaxy disc and compare the UV features with the ones traced by Hα emission. have morphologies consistent with ram pressure being the dominant environmental effect. JO201 is the `UV-brightest cluster galaxy' in Abell 85 (z ∼ 0.056) with knots and streams of star formation in the UV. Dwarf irregular galaxies: dynamics, ram pressure effects Andromeda. The intense burst of star formation happening in the tentacles is the focus of this study. Distances, Chemistry & Star formation in the Local Group: large surveys of resolved stars. Here, we report the ultraviolet (UV) imaging observation of the jellyfish galaxy JO201 obtained at a spatial resolution ∼1.3 kpc. In the case of a galaxy moving through the intergalactic gas, the ram pressure is capable of stripping the galaxy of much of its interstellar gas. ram-pressure stripped tails forming stars in. Their Hα images reveal ionized gas tails up to 100 kpc, which could be hosting ongoing star formation. As the galaxy speeds through, its gas and stars are being stripped away by the tidal forces exerted by the cluster just as the tidal forces exerted by the. Our results predict the environmental signals of RPS in future multiwavelength, high-angular resolution observations: the star formation and gas surface densities will be centralized, and symmetrically enhanced within the stripping radius. Where, how, and why is gas removed from galaxies and what is the effect on galaxy star formation. Jellyfish are cluster galaxies that experience strong ram-pressure effects that strip their gas.
