Description
Two broad components in the strongest UV emission lines of NGC 5548 are identified. The components respond differently to continuum changes. A normal broad (5000 km/sec) line is related to the UV flux, but the data-set only provides an upper limit for the possible lag. The very broad (10000 km/sec) line does not appear to be affected by continuum changes. The physical conditions in the BLR and VBLR seem to be widely different.

    How 4MOST and MOONS will improve constraints on the dynamical masses of Local Group galaxies
    The wide-field spectrographs 4MOST and MOONS are expected to enter operations in late 2024 at the ESO Paranal Observatory. These upcoming survey facilities will play an important role in various fields over the next decade. In particular, both will host surveys aimed at observing Local Group (LG) galaxies. We describe how their scientific

    Star Formation History of the Small Magellanic Cloud: the shell-like structure
    We present the spatially resolved star formation history (SFH) of a shell-like structure located in the northeastern Small Magellanic Cloud (SMC). We quantitatively obtain the SFH using unprecedented deep photometric data (g ∼ 24 magnitude) from the SMASH survey and colour-magnitude diagram (CMD) fitting techniques. We consider, for the first time
