... The disc accretion process is an essential component of star and planet formation theories. ... Much of the detailed knowledge of the physical processes involved in disc accretion have been gained through observations of nearby ( Z ) of the local environment are thought to affect PMS disc accretion rates, and disc evolutionary timescales. ... I measure the accretion rates of these PMS stars using the intensities of the U /H band excess measured through either optical spectra or imaging. ...

Since the first stars and then galaxies formed the Universe has been an immense factory converting neutral gas into stellar material. ... In this seminar I will discuss recent results from the Galaxy And Mass Assembly (GAMA) survey, probing the assembly of stellar mass though both in-situ star formation (as traced by multiple SFR indicators) and interactions (both mergers and interaction induced star-formation) - in galaxies spanning ~4 decades in stellar mass. ...

Implicitly, we will also better understand why most supermassive black holes fail in accreting material. ... 1) Analyse multi-wavelength data for selected galaxies to describe and quantify the different physical phenomena in their centres, and most notably to derive their central supermassive black hole masses....

... In brief: the frequency-dependent radiative transfer equation is solved for a dust under assumption of spherically-symmetric geometry for its distribution taking into account particle size distribution and quantum heating effects for the very small dust particles. ...

Employing the maximum entropy method (MEM) algorithm, we fit interstellar extinction measurements that span the wavelength range 0.125-3 ЮМm. We present a uniform set of MEM model fits, all using the same grain materials, optical constants, and abundance constraints. ... Although such usage is only a first step, the results do provide interesting insight into the use of grain size as a diagnostic of dust environment. ... ADS ] .

So the evidence for Dark Matter is fairly overwhelming. ... Theory: if the Universe is closed then all the luminous matter seen in galaxies contributes only 0.5% of the mass required to eventually halt the expansion . ... This means that galaxies are surrounded by dark matter halos which trapped baryonic gas (e.g. hydrogen) and turned it into stars. ... WIMPS - weakly interacting massive particles created in the extremely early universe . ... Theory 99% of the Universe is Dark Matter . ...

... Amorphous carbonaceous materials can show a great diversity of optical properties due to the variability in their microstructure. ... The differently pyrolized celluloses are representative for a suit of carbonaceous material ranging from strongly disordered (insulating) to graphitized (conducting) material. Figure: Complex refractive index of hydrogenated amorphous carbon prepared by pyrolysis (annealing) of cellulose at different temperatures. ...

... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...
