Using a synchrotron radiation source and a diamond anvil cell, we measured the pressure dependence of the lattice parameters of a polycrystalline Ti4AlN3 sample up to a pressure of 55 GPa. No phase transformations were observed. As observed in Ti3SiC2, Ti3Si0.5Ge0.5C2, and Zr2InC, the compressibility of Ti4AlN3 along the c axis was larger than along the a axis which leads to a decrease in the c/a ratio with increasing pressure. The bulk modulus is 216±2 GPa, with a pressure derivative of 3.84±0.06.

    The brightest events in a time series of cosmological transients obey an observation time dependence which is often overlooked. This dependence can be exploited to probe the global properties of electromagnetic and gravitational wave transients [1, 2]. We describe a new relation based on a peak...

    Blazars are the only (with one or two exceptions) extragalactic objects which were detected and identified at gamma-ray energies so far. It is suspected that most of the unidentified gamma-ray sources may be the blazars as well. Because the entire electromagnetic spectrum of these objects is...

    Attenuation due to the interaction between the electromagnetic wave and the rain medium can be predicted if the relation between the wavelength and the sizes of the raindrops that depend on the rain rate is known. The values of the rain rates were calculated by using a new modification of the...
