Description
We report on the RXTE follow up observations of the black hole candidate IGR J17091-3624 (ATEL #3144, #3159, #3167, #3203) after the report of mHz quasi-periodic oscillations (QPO -- ATEL #3225) and 'heartbeat' oscillations similar to those of GRS 1915+105 (ATEL #3230). The 'heartbeat' oscillations first seen on March 19th (ATEL #3230) at ~25 mHz were also observed in all, except 3, of the subsequent 18 RXTE observations (see below).

    This is major release with several infrastructural changes that will make future development of dynesty easier, as well as significant speedups. The release also deprecated some rarely used options. Major refactor of the code that makes it easier to add new samplers. Major speedup of the uniform sampler when sampling in parallel You can now provide

    Primitive asteroids in the Main Belt possess one of the most pristine inventories of materials in the Solar System. Main Belt primitive asteroids are particularly interesting due to clear evidence of phyllosilicates, i.e., silicates that have encountered liquid water and undergone chemical alteration. Since asteroids are thought to be likely

    NEOMIR: project statut of ESA's space-based infrared mission for NEO detection and early warning
    To warn about potential asteroid or comet impacts, we must first observe and discover these objects through dedicated NEO surveys. Most current and planned surveys are ground-based and use visible light, but they face limitations like weather dependency, limited sky visibility, difficulty detecting at low galactic latitudes, and inability to
