MEGARA is a fiber-fed spectrograph on the 10.4m Gran Telescopio CANARIAS, offering integral field and multi-object spectroscopy with spectral resolutions of R FWHM ∼ 6{,}000, 12{,}000, and 20{,}000. Our team is developing MEGASTAR, an empirical stellar spectral library based on observations from MEGARA. The goal of MEGASTAR is to provide stellar

We use the public code SteParKin to derive their galactic space velocities, which served us to locate them into the different galactic populations. We also identify candidate members in young stellar kinematic groups with SteParKin, LACEwING, and BANYAN Σ based on their kinematics. From the combination of kinematic assignments as a proxy of age and

While NGC 1514 is an elliptical, but complex, planetary nebula at optical wavelengths, it was discovered to have a pair of infrared-bright, axisymmetric rings contained within its faint outer shell during the course of the Wide-field Infrared Survey Explorer all-sky survey. We have obtained JWST mid-infrared imaging and spectroscopy of the nebula

We investigate the capabilities of the mid-infrared instrument (MIRI) of JWST to advance our knowledge of active galactic nucleus (AGN) dust using the spectral fitting technique on an AGN collection of 21 nearby ( $z<0.05$) AGN (7 type-1 and 14 type-2) observations obtained with the medium resolution spectroscopy (MRS) mode. This collection

Studying the birthplaces of massive stars is crucial for understanding the role of clustering in the formation of these objects. Some authors claim that massive stars cannot be born in isolation because the vast majority of them are part of a massive cluster or have been ejected from one of these groups. However, this may be caused by an

We present an spectroscopic study of a sample of bright gamma-ray blazars. Our dataset includes spectra of a sample of about 10 targets, all of them Flat-Spectrum Radio Quasars (FSRQs). The spectra were obtained nearly periodically during the period from 2008 to 2018. We have used a fitting code (PyQSOFit) specifically developed to model the
