We present the most sensitive and detailed view of neutral hydrogen (HI) emission associated with Small Magellanic Cloud (SMC), through combination data from Australian Square Kilometre Array Pathfinder (ASKAP) Parkes (Murriyang), as part Galactic (GASKAP) pilot survey. These GASKAP-HI observations, for first time, reveal HI in SMC on similar physical scales other important tracers interstellar medium, such molecular gas dust. The resultant image cube possesses an rms noise level 1.1 K (1.6...
Abstract Cold neutral hydrogen (H i ) is a crucial precursor for molecular gas formation and can be studied via H absorption. This study investigates absorption in low column density regions of the Small Large Magellanic Clouds (SMC LMC) using Galactic-ASKAP (GASKAP-H survey, conducted by Australian Square Kilometer Array Pathfinder (ASKAP). We select 10 SMC directions outer 18 LMC directions, with four outskirts 14 within main disk. Using radiative transfer method, we decompose emission...
We present the first unbiased survey of neutral hydrogen (HI) absorption in Small Magellanic Cloud (SMC). The utilises pilot HI observations with Australian Square Kilometre Array Pathfinder (ASKAP) telescope as part Galactic ASKAP (GASKAP-HI) project whose dataset has been processed GASKAP-HI pipeline, also described here. This provides spectra towards 229 continuum sources, a 275% increase number sources previously published SMC region, well an improvement quality over previous surveys...
Context . The Galactic ASKAP collaboration (GASKAP) is undertaking an HI emission survey of the 21cm line to map Magellanic system and plane with Australian Square Kilometre Array Pathfinder (ASKAP). One first areas observed in Pilot Phase I was Small Cloud (SMC). Previous surveys SMC have uncovered new structures periphery SMC, along relatively low column density lines sight. Aims In this work we aimed uncover phase distribution three distinct SMC. This will add constraints on existence...
