We report about the fast Nova Sgr 2016 N.4 being surprisingly trapped in a long-lasting and bright plateau (Delta(I)>=10mag above quiescence), six years past the nova...

In the framework of the GIARPS High-resolution Observations of T Tauri stars (GHOsT) project, we study the accretion properties of 37 classical T Tauri stars of the...

Achernar, the closest and brightest classical Be star, presents rotational flattening, gravity darkening, occasional emission lines due to a gaseous disk, and an extended polar...

Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia-RVS spectral window between 846 and...

We present photometric and spectroscopic observations of the Type IIn supernova SN 2019zrk (a.k.a. ZTF 20aacbyec). The SN shows a >~100 day precursor, with a slow rise,...

We developed a metal-poor candidate selection method based on flux-ratios from the BP/RP Gaia spectra, using simulated synthetic spectra. We found a relation between the...

The log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at Vilspa. It was constructed by using verified data from the...

The log contains data from January 26, 1978 through Dec. 92. It is sorted by right ascension.

Funded by NASA as part of its Origins program, FUSE was developed in collaboration with the space agencies of Canada and France, and is being operated for NASA by the Johns...

The log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at Vilspa. It was constructed by using verified data from the...

The Tubingen Echelle Spectrograph (TUES), designed and managed at the University of Tubingen, flew on the Orbiting and Retrievable Far and Extreme Ultraviolet Spectrograph...

The Hopkins Ultraviolet Telescope HUT was one of three ultraviolet instruments of the ASTRO-1 mission flown on the space shuttle Columbia during 2-10 December 1990. 106...

This catalog contains the 278 low-resolution (R~20) near-infrared (1.8-5.3micron) spectra of diffuse sky covering a wide range of galactic and ecliptic latitudes with the...

We estimate the number counts of line emitters at high redshift and their evolution with cosmic time based on a combination of photometry and spectroscopy. We predict the...

We combine samples of nearby galaxies with Herschel photometry selected on their dust, metal, HI and stellar mass content, and compare these to chemical evolution models in...

We report the results of multicolour observations of 30 E/S0 galaxies with dust lanes. For each galaxy we obtained broad-band images and narrow-band images using interference...

We present a comparative study of the near-infrared (NIR) H_2_ line emission from five regions near hot young stars: Sharpless 140, NGC2023, IC63, the Horsehead Nebula, and the...

The observed scale heights of extraplanar diffuse ionized gas (eDIG) layers exceed their thermal scale heights by a factor of a few in the Milky Way and other nearby edge-on...

We present the results of a ~250arcmin^2^ mapping of the 205um [NII] fine-structure emission over the northern Carina Nebula, including the Car I and Car II HII regions. Spectra...

The Seyfert 1 galaxy Zw 229-015 is among the brightest active galaxies being monitored by the Kepler mission. In order to determine the black hole mass in Zw 229-015 from...
