A novel black hole mass scaling relation based on coronal gas, and its dependence with the accretion disc

Almudena Prieto et al.

Summary: A novel black hole mass scaling relation has been discovered, with the effective temperature of the disc being identified as one of the main drivers of this relationship. This relation is valid over the BH mass interval of 10^6-10^8 M☉.

The Physics of the Coronal-line Region for Galaxies in Mapping Galaxies at Apache Point Observatory

James Negus et al.

Summary: The study investigates the nature and extent of the coronal-line region (CLR) in galaxies, finding that the CLR is more extended than previously thought and shows signs of shocks through electron temperatures. The production of coronal lines is believed to be primarily driven by ionizing photons emitted by the central continuum source, with energetic shocks as an additional ionization mechanism for the most extended CLR regions measured.

Near-infrared Studies of Nova V1674 Herculis: A Shocking Record Breaker

C. E. Woodward et al.

Summary: This study presents near-infrared spectroscopy of Nova Herculis 2021, revealing a rich emission line spectrum with strong coronal line emissions. The hydrogen ejected mass is estimated to have an upper limit of 1.4 x 10(-3) solar masses, and coronal lines appeared at day 11.5, the earliest onset observed for any classical nova. The vexing problem of whether collisional ionization or photoionization is responsible for coronal emission in classical novae can be resolved by correlating the temporal sequence of X-ray supersoft phase and near-infrared coronal line emission.

Coronal-line forest active galactic nuclei - I. Physical properties of the emission-line regions

F. C. Cerqueira-Campos et al.

Summary: Coronal-line forest (CLiF) active galactic nuclei (AGNs) are not a separate category of AGNs, but rather an extension to the low/high ends of the distribution within the AGN class. The physical conditions of the NLR gas suggest that the ionization mechanism is primarily associated with photoionization by the AGN.

Near-infrared Coronal Line Observations of Dwarf Galaxies Hosting AGN-driven Outflows

Thomas Bohn et al.

Summary: The study confirms the presence of AGN activity in 55% of the nine Ma < 1010 Me dwarf galaxies, and finds a similar CL detection rate to larger galaxies hosting AGNs. By analyzing the kinematics of the CL region and the scaling of gas velocity with ionization potential, the study investigates the connection between CLs and galaxy-wide outflows. The faster outflow velocities measured in [Si VI] compared to those in [O III], and the lack of J-band CN absorption features, provide further evidence that these outflows are driven by AGNs in low-mass galaxies.

Relics of Supermassive Black Hole Seeds: The Discovery of an Accreting Black Hole in an Optically Normal, Low Metallicity Dwarf Galaxy

Jenna M. Cann et al.

Summary: The detection and characterization of supermassive black holes in local low mass galaxies is essential for understanding their origins. Recent studies have found an indicator of AGNs in a low mass, low metallicity galaxy, demonstrating the importance of infrared indicators in identifying AGNs when optical diagnostics are inconclusive.

Gemini NIFS survey of feeding and feedback in nearby active galaxies - IV. Excitation

Rogemar A. Riffel et al.

Summary: In this study, J- and K-band integral field spectra of six luminous Seyfert galaxies were used to investigate the gas excitation within the galaxies. The results showed that shocks are the main excitation mechanism for H-2 gas in these galaxies, while AGN radiation plays a role in the emission lines in the AGN region of the diagnostic diagram.

Reverberation in Tidal Disruption Events: Dust Echoes, Coronal Emission Lines, Multi-wavelength Cross-correlations, and QPOs

Sjoert van Velzen et al.

Summary: Stellar tidal disruption events are typically discovered through transient emissions, but they can be reprocessed by gas or dust resulting in multiple reverberation signals. These signals have been detected and provide insights into important properties of TDEs. Anticipation is high for the detection of more reverberation signals with the next generation of X-ray and infrared instruments.

Broad He I 1.08-μm absorption from the obscurer in the active galaxy NGC 5548

Conor Wildy et al.

Summary: The study found a massive obscuration event at the nucleus of the active galaxy NGC 5548, supporting the existence of warm absorber (WA) and obscurer. The experiment also indicates the impact of helium recombination on the physics of WA gas, but suggests that the reality might be more complex.
