Elliptical Galaxies and Bulges of Disk Galaxies: Summary of Progress and Outstanding Issues
This is the summary chapter of a review book on galaxy bulges. Bulge properties and formation histories are more varied than those of ellipticals. I emphasize two advances: 1 - "Classical bulges" are observationally indistinguishable from ellipticals ...

DUST-DRIVEN WIND FROM DISK GALAXIES [PDF]
We study gaseous outflows from disc galaxies driven by radiation pressure on dust grains. We include the effect of bulge and dark matter halo and show that the existence of such an outflow implies a maximum value of disc mass-to-light ratio. We show that the terminal wind speed is proportional to the disc rotation speed in the limit of a cold gaseous ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

On the Orbital Evolution of Binaries with Polar Circumbinary Disks
Binaries occur in many astrophysical systems, from young protostellar binaries in star-forming regions to supermassive black hole binaries in galaxy centers.

The Mechanism and Timescale of Nodal Precession: Two Nuclear Stellar Disks in the Galactic Center
A dynamical model of interacting nuclear stellar rings in the central parsec of our Galaxy is constructed. We discuss the physical sources of nodal precession and of the associated time scales.

ABSTRACT The heat equation is often used to inpaint dropped data in inpainting‐based lossy compression schemes. We propose an alternative way to numerically solve the heat equation by an extended Krylov subspace method. The method is very efficient with respect to the computation of the solution of the heat equation at large times.

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4
We study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...

ABSTRACT This study evaluated the preservative potential of essential oils (EOs) in bakery products by identifying fungal contaminants in bread, testing the in vitro antifungal activity of a mixture of cinnamon, clove, and bay leaf EOs, and assessing their effectiveness in extending shelf life. Fungal identification revealed the presence of Penicillium,
