ABSTRACT We reliably extend the stellar mass–size relation over 0.2 ? z 2 to low mass galaxies by combining depth of Hubble Frontier Fields with large volume covered CANDELS. Galaxies are simultaneously modelled in multiple bands using tools developed MegaMorph project, allowing robust size (i.e. half-light radius) estimates even for small, faint, and high redshift galaxies. show that above 107...

We present optical spectroscopy of the dwarf nova HL Canis Majoris over a span of four years. The observations were made during standstill, outburst, and quiescence. We determine an orbital period of 0.2167867 ± 0.0000017 days, based on radial velocities determined from Hα, Hβ, and HeI λ 5876 emission. We also present equivalent widths of the spectral features in outburst and in quiescence. Sub...

Neurogenic niches in the adult mammalian brain are composed of heterogeneous populations of neural stem cells. In this issue of Neuron, Codega et al. (2014) isolate quiescent neural stem cells from the adult subventricular zone and demonstrate their stem cell characteristics.

The seasonal change of free abscisic acid (ABA) and indole-3-acetic acid (IAA) and their relationship with the cambial activity in Eucommia ulmoides trees were investigated by ABA and IAA immunolocalization using primary polyclonal and rhodamine-red fluorescing secondary antibodies, ABA and IAA quantification using high performance liquid chromatography (HPLC), and systematic monitoring of vasc...
