Origins of coplanar counterrotating stellar disk components in late-type galaxies
Astronomy & AstrophysicsContext. Understanding galaxy evolution is key to explaining the structures we observe in the present-day Universe. Counterrotating stellar disks, i.e., co-spatial stellar disks rotating with opposite angular momentum, have been proposed as signatures of

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events
Astronomische Nachrichten, Volume 347, Issue 5, June 2026.ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars
The Astrophysical Journal LettersStudying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves
Astronomische Nachrichten, Volume 347, Issue 5, June 2026.ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).

The Astrophysical JournalGamma-ray bursts (GRBs), both from the merger of binary compact objects (short GRBs) and the collapse of massive stars (long GRBs), are expected to occur in dense environments, e.g., the accretion disks of active galactic nuclei (AGNs).

The Astrophysical JournalMagnetically arrested disks (MADs) have attracted much attention in recent years. The formation of MADs is usually attributed to the accumulation of a sufficient amount of dynamically significant poloidal magnetic flux.

Insights from Analytical Theory of Eccentric Circumbinary Disks
The Astrophysical JournalEccentric cavities in circumbinary disks precess on timescales much longer than the binary orbital period. These long-lived steady states can be understood as trapped modes in an effective potential primarily determined by the binary quadrupole and the ...

Disk Truncation Triggers Relativistic Jet Launching of a Highly Accreting Supermassive Black Hole
The Astrophysical Journal LettersRelativistic jets are among the most energetic phenomena in the Universe and influence galaxy evolution through energetic feedback, yet the physical connection between accretion flows and jet launching remains unresolved.
