This is a talk given at lunch time, usually in the conference room at noon.
The stellar halos of galaxies provide records of their past, including the early epochs of star formation and the accretion of satellites. The clearest record is written in the space of chemodynamics (stellar orbits and abundance patterns), which is very challenging to observe beyond the Milky W
Laboratory astrophysics emerged as a novel way to test models of distant or inaccessible astrophysical objects.
WINERED is a near-IR spectrograph for a wide wavelength range of 0.9-1.35 micron with the resolving power of 28,000. Higher resolution modes with the resolution up to 70,000 are available but for either Y band (0.96-1.11 micron) or J band (1.14-1.35 micron) at one time.
The CIII] emission doublet (1907,1909 Angstroms) has been proposed as an alternative to Lyman-alpha in redshift confirmations of galaxies at z > 6 since it is not atte
In this talk I utilize Self Organizing Maps (SOMs), a class of unsupervised neural networks, for dealing with specific challenges in astrophysics from meeting the cosm
