3. The detection of diffuse HI emission in the CGM of NGC 891 and NGC 4565 away from their principal axes, unveiling an azimuthally asymmetric neutral inner (<50 kpc) CGM (Rickel, Das et al. 2026, ApJ)
The CGM along major-axis pointings co-rotates with the HI disk and traces an inflow along minor-axis pointings.Â
2. The detection of extended (~100 kpc) diffuse HI emission in the CGM of NGC 891 and NGC 4565 along their principal axes (Das et al. 2024, MNRAS)
1. Proof-of-concept: Diffuse extended (~100 kpc) HI emission is detected in the CGM of NGC 891 and NGC 4565 (Das et al. 2020, ApJ, 898, 15)
We are now extending the study to a larger galaxy sample. Stay tuned for new and exciting results!
