Description
The authors have made observations of the spectrum of comet Halley on various dates between September 1985 and December 1986, obtaining multipositional long-slit absolute spectrophotometry of the inner region of the coma in the visible range. They present a study of the emission in the 3883 Å line of the (0-0) transition of CN. The observed CN surface brightness spatial distribution is used to obtain the distribution of molecules and is fitted to Haser's model to obtain scale lengths.

    Deep HST Imaging Favors the Bulgeless Edge-on Galaxy Explanation for the Hypothetical Stellar Wake Created by a Runaway Supermassive Black Hole
    A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a bulgeless edge-on galaxy. We report on new very deep Hubble Space Telescope imaging that seems to be in tension with the SMBH runaway scenario but is consistent with the bulgeless edge-on

    The molecular gas perspective on the growth and death of H emitters in the Spiderweb protocluster at Alpha z=2.16
    Galaxy clusters at low redshift are dominated by massive quiescent galaxies hosting stellar populations 10 Gyrs old, indicating that they were formed in the early universe when clusters were still in the process of being assembled (i.e., protoclusters). The rapid growth of galaxies within protoclusters is driven by the efficient transformation of

    Magnetohydrodynamic Processes in Solar Plasmas
    Magnetohydrodynamic Processes in Solar Plasmas provides a comprehensive theory and practice of basic plasma processes in the Sun and heliosphere. It deals with the basic dynamics of the Sun from its interior up to its outer atmosphere in the framework of Magnetohydrodynamics. Topics covered include essential phenomena in the solar interior such as
