Helical Strands in the Jetlike Narrow-Line Region of ESO 428-G14 [PDF]
The Astrophysical Journal, 1996 We present HST/WFPC2 images of the narrow line region (NLR) of the Seyfert 2 galaxy ESO 428-G14 (0714-2914, M4-1). The NLR consists of many individual, thin strands, which are very closely related to the radio jet and produce a highly complex yet ordered structure.

Dust beyond the torus: revealing the mid-infrared heart of local Seyfert ESO 428-G14 with JWST/MIRI [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT Polar dust has been discovered in a number of local active galactic nuclei (AGN), with radiation-driven torus models predicting a wind to be its main driver. However, little is known about its characteristics, spatial extent, or connection to the larger scale outflows.

Powerful mechanical-driven outflows in the central parsecs of the low-luminosity active galactic nucleus ESO 428-G14 [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2018 ABSTRACT Low-luminosity Active Galactic Nuclei (LLAGNs) are characterized for low-radiative efficiency, much less than one percent of their Eddington limit. Nevertheless, their main energy release may be mechanical, opposite to powerful AGN classes like Seyfert and Quasars.

Minimally invasive approaches for implant-supported overdentures in the atrophied mandible. [PDF]
GerodontologyObjectives The study compares three minimally invasive approaches for the retention of implant supported mandibular complete dentures, particularly focusing on patient satisfaction. Background The McGill Consensus Statement recommends restoration of the edentulous mandible with an overdenture retained on two implants.

Mean–variance relationship and uncertainty [PDF]
Seonmul yeongu, 2022 This study investigates the impact of uncertainty on the mean-variance relationship. We find that the stock market's expected excess return is positively related to the market's conditional variances and implied variance during low uncertainty periods ...
