Context. Galaxy superclusters are the largest systems in the Universe that can give us information about the formation and evolution of the cosmic web. Aims: We...
Bottom-heavy initial mass function in a nearby compact L★ galaxy
We present orbit-based dynamical models and stellar population analysis of Sloan Digital Sky Survey J151741.75-004217.6, a low-redshift (z = 0.116) early-type...
Bounds on Lorentz Invariance Violation from MAGIC Observation of GRB 190114C
On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever...
Bow shocks, nova shells, disc winds and tilted discs: the nova-like V341 Ara has it all
V341 Ara was recently recognized as one of the closest (d ≃ 150 pc) and brightest (V ≃ 10) nova-like cataclysmic variables. This unique system is surrounded by...
Bow-shocks and possible jet-shell interaction in the planetary nebula M 2-48
Deep narrow band CCD images in the Hα , [O Iii] lambda5007 Ä, [N Ii] lambda6584 Ä, and [S Ii] lambda6717 +31 Ä emission lines have been obtained for the...
Bowen emission from Aquila X-1: evidence for multiple components and constraint on the accretion disc vertical structure
We present a detailed spectroscopic study of the optical counterpart of the neutron star X-ray transient Aquila X-1 during its 2011, 2013 and 2016 outbursts. We...
Bowen Fluorescence from the Companion Star in X1822-371
We present clear evidence for the motion of the companion star in the low-mass X-ray binary (LMXB) X1822-371. We detect N III λ4640 emission moving in antiphase...
BOWIE-ALIGN: A JWST comparative survey of aligned versus misaligned hot Jupiters to test the dependence of atmospheric composition on migration history
A primary objective of exoplanet atmosphere characterization is to learn about planet formation and evolution, however, this is challenged by degeneracies. To...
BOWIE-ALIGN: how formation and migration histories of giant planets impact atmospheric compositions
Hot Jupiters present a unique opportunity for measuring how planet formation history shapes present-day atmospheric composition. However, due to the myriad...
