Sgr A*, the supermassive black hole (SMBH) in our Galaxy, is dormant today, but it should have gone through multiple gas-accretion episodes in the past billions of years to grow to its current mass of 4 × 106 M⊙. Each episode temporarily ignites the SMBH and turns the Galactic Center into an active galactic nucleus (AGN). Recently, we showed that the AGN could produce large amounts of hard X-rays that can penetrate the dense interstellar medium in the Galactic plane. Here we further study the…

Chemical modeling of the complex organic molecules in the extended region around Sagittarius B2

The chemical differentiation of seven COMs in the extended region around Sgr B2 has been observed: CH$_2$OHCHO, CH$_3$OCHO, t-HCOOH, C$_2$H$_5$OH, and CH$_3$NH$_2$ were detected both in the extended

The impact of tidal disruption events on galactic habitability

Tidal disruption events (TDEs) are characterized by the emission of a short burst of high-energy radiation. We analyse the cumulative impact of TDEs on galactic habitability using the Milky Way as



Models of gas-grain chemistry in dense interstellar clouds with complex organic molecules

Models of the chemistry of dense interstellar clouds are presented in which both gas-phase and grain-surface chemistry occur. The dust grain and gas temperatures are fixed at 10 K, and the gas

Fossil imprint of a powerful flare at the galactic center along the magellanic stream

The Fermi satellite discovery of the gamma-ray emitting bubbles extending 50° (10 kpc) from the Galactic center has revitalized earlier claims that our Galaxy has undergone an explosive episode in

X-ray ionization and the Orion molecular cloud

The observed X-ray sources near the core of the Orion molecular cloud are sufficient to supply all the ionization that is needed to drive the molecular chemistry throughout that portion of the cloud


Molecular gas chemistry in AGN I. The IRAM 30 m survey of NGC 1068

There is observational evidence that nuclear winds and X-rays can heavily influence the physical conditions and chemical abundances of molecular gas in the circumnuclear disks (CND) of Active

Herschel observations of water vapour in Markarian 231

The Ultra luminous infrared galaxy (ULIRG) Mrk 231 reveals up to seven rotational lines of water (H2O) in emission, including a very high-lying (Eupper = 640 K) line detected at a 4 sigma level,


Virtually all detailed gas-phase models of the chemistry of dense interstellar clouds exclude polycyclic aromatic hydrocarbons (PAHs). This omission is unfortunate because from the few studies that

The Galactic Center: a laboratory for AGN?

Summary.This paper reviews the physical state of stars and Interstellar Matter in the Galactic Bulge (radius $R \sim 0.3 - 3\,$kpc from the dynamical center of the Galaxy), in the Nuclear Bulge ( $R

The Physics and Chemistry

Four sets of experiments are described that use either the reduced gravity or the large pumping speeds and vast reduced pressure domains available on or outside the station. The scientific rationale
