The evolution of cosmic structures, the formation and growth of the first black holes and the connection to their baryonic environment are key unsolved problems in astrophysics. The X-ray Athena mission and the gravitational-wave Laser Interferometer Space Antenna (LISA) offer independent and complementary angles on these problems.
The color–stellar mass-to-light ratio relation (CMLR) is a widely accepted tool for estimating the stellar mass (M *) of a galaxy. However, an individual CMLR tends to give distinct M * for a same galaxy when it is applied in different bands. Examining five representative CMLRs from the literature, we find that the difference in M * predicted in different bands from optical to near-infrared by a CMLR is 0.1 ~ 0.3 dex.

The effect of the magnetic impurities on the charge transport in a magnetic topological ultra-thin film (MTF) is analytically investigated by applying the semi-classical Boltzmann framework through a modified relaxation-time approximation.
The mode field intensity, spot size, central peak intensity evolution and adiabaticity are calculated for different points along the transition of an optical fibre taper that adiabatically tapers from the standard 125 nm down to 1 µm and then to 440 nm diameter for low loss operation at 1550 nm wavelength.
