  with Adi Zitrin

  Abstract/Description: Early observation of JWST have revealed an unexpected population of extremely red and
  compact high redshift sources, termed Little Red Dots (LRDs). Characterized by their distinctive
  "V-shape" Spectral Energy Distribution (SED), and broad emission lines, LRDs are often
  considered to be Active Galactic Nuclei (AGN). However, their exact nature remains uncertain.
  In this work I develop a custom SED fitting pipeline for LRDs, adopting the notion they are
  AGN. Using photometric data, the pipeline estimates the physical properties of the object, such
  as redshift, intrinsic luminosity, strength of undergoing dust extinction, and the temperature of
  that dust.
  We then present a sample of 26 LRD candidates selected from the MS0451 field and the
  PEARLS project, utilizing a well-defined set of color and morphology selection criteria. From
  our analysis, 12 sources are identified as promising LRD candidates, six shows tentative consistency
  but require further data, five remain inconclusive, and three are ruled out. With the aid
  of our pipeline, the AGN model places these objects at redshifts z ∼ 2.63 − 8.36, with dust
  extinction Av ∼ 1.1 − 5.4, and intrinsic luminosities in the range L ∼ 1042−44erg s−1.
  Our pipeline is validated against two established LRD sources, and shows promise for future
  use in estimating physical parameters of LRD sources. This pipeline can be extended with
  additional components for the extinction process as recent data implies.
