What can we learn from the Nitrogen abundance of High-z galaxies?
Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +9
We present measurements of the gas-phase Oxygen and Nitrogen abundances obtained by applying the direct method to JWST NIRspec spectroscopy for 6 galaxies at redshift g…
Uncertainty of line-of-sight velocity measurement of faint stars from low and medium resolution optical spectra
László Dobos, Alexander S. Szalay, Tamás Budavári +3
Massively multiplexed spectrographs will soon gather large statistical samples of stellar spectra. The accurate estimation of uncertainties on derived parameters, such as line-of-s…
Triangulum IV: A Possible Ultra-Diffuse Satellite of M33
Itsuki Ogami, Yutaka Komiyama, Masashi Chiba +8
We report the detection of a dwarf satellite candidate (Triangulum IV: Tri IV) of the Triangulum galaxy (M33) using the deep imaging of Subaru/Hyper Suprime-Cam (HSC). From the app…
