Although rare within the context of 30 000 species of extant fishes, scale-feeding as an ecological strategy has evolved repeatedly across the teleost tree of life. Scale-feeding (lepidophagous) fishes are diverse in terms of their ecology, behaviour, and specialized morphologies for grazing on scales and mucus of sympatric species. Despite this diversity, the underlying ontogenetic changes in ...

(abridged) Magnetic fields are fundamental to the accretion dynamics of protoplanetary disks and they likely affect planet formation. Typical methods study magnetic field morphology observe polarization dust or spectral lines. However, it has recently become clear that dust-polarization in ALMA's regime does not always faithfully trace structure disks, which leaves line as a promising method fo...

Parsec-scale massive black hole binaries (MBHBs) are expected to form in hierarchical models of structure formation. Even though different observational strategies have been designed detect these systems, a theoretical study is further guide for their search and identification. In this work, we investigate the hosts properties electromagnetic signatures holes gravitationally bound on parsec-sca...
