Title: Statistics for Galaxy Outflows at z∼6−9 with Imaging and Spectroscopic Signatures Identified with JWST/NIRCam and NIRSpec Data
Speaker: Capucine
Summary: Zhang et al look at 61 galaxies between z=5.4 and 8.9, both using NIRSpec spectroscopy and NIRCam imaging, to study the outflow properties in their sample. They make a study of both spatially extended [OIII] emission in the imaging (5/61) and broad component in the emission line, indicating the presence of fast winds (5/30); including one galaxy that has both spatially extended emission and a broad component in the spectra. They compute the ratio of the wind velocity over the escape velocity of the galaxies' halo, and find that none of the detected outflows have velocities high enough to eject gas outside the gravitational well of the halo. They conjecture that they are witnessing the different phases of a star forming outflow event (as shown in the figure, where in the beginning outflows can only be seen in the spectra, then an extended emission is observed, and finally it falls back into the galaxy). They also compare their outflow incidence in the extended emission at high redshift to local studies, and find an increase in the incidence broadly consistent with the increase in major merger rate; but fail to observe a similar increase in incidence with the "spectral" outflows (Figure 11).
Title: The MOSDEF-LRIS Survey: Detection of Inflowing Gas Towards Three Star-forming Galaxies at z ~ 2
Speaker: Daizhong
Summary: The authors observed wide rest-UV absorption lines in three MOSDEF galaxies. They argue that these are the signature of inflowing gas from the recycled metal-enriched gas with a large velocity ~250-500 km/s, instead of pristine gas from the CGM.Title: A 3D view on the local gravitational instability of cold gas discs in star-forming galaxies at 0 ≲ z ≲ 5
