Overview

A multiwavelength study reveals the dynamics of nuclear outflows in NGC 4395, indicating significant impact on surrounding gas.

Key Points

  • This research aims to investigate the characteristics and dynamics of nuclear outflows in the dwarf Seyfert galaxy NGC 4395.
  • Conducted a multiwavelength study using JWST/NIRSpec, ALMA, and Gemini/GMOS data.
  • Analyzed emissions from ionized and molecular gas, including various spectral lines.
  • Modelled the H2 rotational lines to identify warm/hot and cold gas components.
  • Identified three warm/hot molecular components with temperatures between 580 K and 2900 K.
  • Measured outflow velocities ranging from 127 to 716 km/s, indicating a stratified biconical structure.
  • Determined a significantly larger mass outflow rate for cold gas compared to warm/hot and ionized phases.
