1. 1. Active Galactic Nuclei in galaxy surveys : Empirical paths to the fiery hearts of cosmic beasts

   Författare :Beatriz Villarroel; Andreas J. Korn; Takis Konstantopoulos; Moshe Elitzur; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi;

   Sammanfattning : Some galaxies emit excessive amounts of light from their centers, caused by accretion of gas onto super-massive black holes (SMBH). These galactic cores are often referred to as Active Galactic Nuclei (AGN) and they come in many different forms, distinguishable by their emission properties. LÄS MER

3. 2. The descent of damselflies and variation in relation to sex

   Författare :Beatriz Willink Castro; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sexual conflict; development; diversification; pleiotropy; correlational selection; damselfly;

   Sammanfattning : Sexual conflict over mating shapes the interactions between males and females in many animals and is also responsible for dramatic adaptations in both sexes. In some species of pond damselflies (Odonata:Coeangrionidae), sexual conflict maintains discrete female-limited colour morphs over multiple generations and within populations. LÄS MER
