We collected the largest spectroscopic catalog of RR Lyrae (RRLs) including ≍20,000 high-, medium-, and low-resolution spectra for ≍10,000 RRLs. We provide the analytical forms of radial velocity curve (RVC) templates. These were built using 36 RRLs (31 fundamental-split into three period bins-and five first-overtone pulsators) with well-sampled

IGR J17285-2922 is a known X-ray binary with a low peak 2-10 keV X-ray luminosity of ~ 10 36 erg s -1 during outburst. IGR J17285-2922 exhibited two outbursts in 2003 and 2010 and went into outburst again in 2019. We have monitored this ~ 4-month long 2019 outburst with Swift in X-ray and the Very Large Array in radio. We have also obtained four

Context. While some galactic bars show recent massive star formation (SF) along them, some others do not. Whether bars with low level of SF are a consequence of low star formation efficiency, low gas inflow rate, or dynamical effects remains a matter of debate. Aims: In order to study the physical conditions that enable or prevent SF, we perform a
