57. Exploring Hard X-ray Selected AGN Populations with ExSeSS and SDSS-V

Jack Delaney

8/2/23, 4:00 PM

I will present results from the Extragalactic Serendipitous Swift Survey (ExSeSS) along with initial results from an SDSS-V open-fibre program that is providing spectroscopic follow-up of a bright, hard X-ray selected sub-sample. The ExSeSS sample has enabled us to measure the differential number counts of X-ray sources as a function of 2-10~keV flux, providing insight into the population of...

58. SDSS Spectroscopy of Chandra Source Catalog Counterpart

Paul Green

8/2/23, 4:12 PM

With release imminent, the Chandra Source Catalog version 2.1 (CSC2.1) provides nearly four hundred thousand well-characterized X-ray sources observed by Chandra from launch (1999) through 2021, covering about 800 square degrees. The Sloan Digital Sky Survey V (SDSS-V) is obtaining new optical and infrared spectroscopy of Chandra source counterparts in fields across the entire sky. SDSS-V is...

60. Chemical Homogeneity Of Open Clusters In The Milky Way

Amaya Sinha

8/2/23, 4:24 PM

Stars in an open cluster are assumed to have formed from a broadly homogeneous distribution of gas, implying that they should be chemically homogeneous. We test this assumption by quantifying chemical scatter in Milky Way open clusters in a broad set of abundances, in order to probe a variety of nucleosynthetic pathways to learn about ISM pollution and gas-mixing in molecular clouds. We use...

55. Spectral Properties of Young Stars in Nearby Star Forming Regions. The road from APOGEE-2 to MWM

Carlos Román Zúñiga

8/2/23, 4:36 PM

We present the APOGEE-2 star forming regions catalog (Román-Zúñiga et al 2023) which is based on spectral labels (Teff, Logg, [Fe/H] from the APOGEE Net II neural network (Sprague et al 2022). We present preliminary follow-up work on the relation between young star and gas kinematics in 3 regions (Rosette, Cygnus-X, Vela Ridge). We also present preliminary results on applying the APOGEE...
