Room: E.0.11 Abstract: Gamma Ray Bursts (GRBs), commonly associated with Broad-Line supernovae type Ic (SNe Ic-BL), and Super Luminous Supernovae (SLSNe) are the brightest astronomical phenomena in the Universe, located in hearts of star-forming regions. These violent explosions not only are valuable laboratories for extreme physical conditions, but also are powerful tracers of fundamental processes in galaxy formation and evolution. Although the link between GRBs/SLSNe and massive stars is well established, the physical properties of the stellar population that gives rise to these rare explosions and the interstellar medium conditions in which they form remain poorly constrained. Our recent studies indicate a possible link between rare galaxy dynamics and the formation of massive star progenitors of these violent events. If this be the case, the extreme conditions induced by galaxy dynamics (due to external/internal effects) could be the factors singling out the environment in which these bright transients form. The large-scale galaxy dynamics can be traced through the distribution and kinematics of neutral gas. I will describe our ongoing survey of neutral gas in z < 0.1 host galaxies, designed to investigate the structure of gas in the close environment of SNe Ic-BL / GRBs / SLSNe, and to explore the extreme conditions responsible for the formation of the progenitors of these explosions. I will in particular focus on our findings for the host galaxies of SN 1998bw / GRB 980425, SN 2017iuk / GRB 171205A, SLSN PTF10tpz, and AT2018cow, studied as a part of this survey, supporting the likely connection between massive star explosions and peculiar dynamics. Such a connection being commonplace will set these energetic transients as tracers of galaxies with extreme dynamics and also will help improve our understanding of the progenitor stars of these events.
