(simplified) Results on the properties of warm H2 in 57 normal galaxies are derived from H2 rotational transitions, obtained as part of SINGS. This study extends previous extragalactic surveys of H2, the most abundant constituent of the molecular ISM, to more common systems (L_FIR = e7 to 6e10 L_sun) of all morphological and nuclear types. The S(1) transition is securely detected in the nuclear regions of 86% of SINGS galaxies with stellar masses above 10^9.5 M_sun. The derived column densities of warm H2 (T > ~100 K), even though averaged over kiloparsec-scale areas, are commensurate with those of resolved PDRs; the median of the sample is 3e20 cm-2. They amount to between 1% and >30% of the total H2. The power emitted in the sum of the S(0) to S(2) transitions is on average 30% of the [SiII] line power, and ~4e-4 of the total infrared power (TIR) within the same area for star-forming galaxies, which is consistent with excitation in PDRs. The fact that H2 emission scales tightly with PAH emission, even though the average radiation field intensity varies by a factor ten, can also be understood if both tracers originate predominantly in PDRs, either dense or diffuse. A large fraction of the 25 LINER/Sy targets, however, strongly depart from the rest of the sample, in having warmer H2 in the excited states, and an excess of H2 emission with respect to PAHs, TIR and [SiII]. We propose a threshold in H2 to PAH power ratios, allowing the identification of low-luminosity AGNs by an excess H2 excitation. A dominant contribution from shock heating is favored in these objects. Finally, we detect, in nearly half the star-forming targets, non-equilibrium ortho to para ratios, consistent with FUV pumping combined with incomplete ortho-para thermalization by collisions, or possibly non-equilibrium PDR fronts advancing into cold gas.


A son who saw a police officer hold a gun to his father's head. A husband whose wife was pulled over driving a Bentley. These unsettling scenes are among the stories from some of the NFL's marquee players, multi-millionaires sharing tales of racial profiling by law enforcement. It is a troubling concern for people of color that has been at the center of the protests begun in August 2016 by former San Francisco 49ers quarterback Colin Kaepernick. The protests have waned, but the ongoing issue for players — and the black communities they come from — has not. The Associated Press surveyed 56 of the 59 black players at last weekend's Pro Bowl game as part of its look at how African-American athletes have long used their sports platforms to impact social and political change. The AP asked the players whether they or someone they knew have ever experienced racial profiling. All said yes. "You can probably ask any black man out here and the answer is yes," said Jacksonville Jaguars defensive tackle Malik Jackson. "It's not like this is just starting today or a new thing. It's gone on for a long time. I think African-American men have been (victims) of racial profiling for a long time, by either the things they wear or just by the color of their skin." ___ EDITOR'S NOTE: African-American athletes have used their sports platforms for more than 100 years to impact social and political change. As part of AP's coverage plans for Black History Month, we will take a multi-platform look at look at how many have and continue to engage in activism, from Jack Johnson, to Muhammad Ali to Colin Kaepernick. ___ In protesting, Kaepernick and others attempted to highlight the killings of unarmed black men by police, an issue brought into the national spotlight by Black Lives Matter activists after the shooting death of Michael Brown in Ferguson, Missouri, in 2014. But the message was quickly overtaken by fans offended by the players' decision to kneel during the anthem. "That was the main thing with the protests, to bring awareness so people know what's going on," said Jaguars cornerback Jalen Ramsey. "That's the first step to trying to fix the situation." NFL players who have protested this season have been in the minority, and protests waned as the season went on. Some players are focusing on ways of addressing injustice off the field. "If it affects that many people by taking a knee, just stand up, it's that simple," said


A new model for the explanation of the high frequency quasi-periodic oscillations (QPOs) in pulsars, black holes and white dwarfs is presented. Three circular tori are assumed to be present around the star: an inner torus with charge $Q_i$, an outer torus with charge $Q_o$ and a torus with electrically neutral mass $m_m$ in the middle, whereas the star bears a charge $Q_s$ ($Q_o$ and $Q_s$ have the same sign, $Q_i$ the opposite one). The frequency $\nu_m$ of the mass current is approximately given by the Kepler frequency, whereas the frequencies of $Q_i$ and $Q_o$, $\nu_i$ and $\nu_o$, respectively, are calculated from classical mechanics and Coulomb's law. For the explanation of the low frequency QPOs in pulsars and black holes a special interpretation of the gravitomagnetic theory may be essential. From the latter theory four new gravitomagnetic precession frequencies are deduced, which may be identified with the observed low frequency QPOs. Predictions of the presented model are compared with observed high frequency and low frequency QPOs of the pulsars SAX J1808.4--3658, XTE J1807--294, IGR J00291+5934, SGR 1806--20 and the black hole XTE J1550--564. In addition, charge flow near the pole of pulsars may explain frequency drift of burst oscillations. Moreover, charge flow at the equator of SAX J1808.4--3658 may be the cause of the enigmatic 410 kHz QPO. Furthermore, the Lense-Thirring frequency is discussed and a modified formula is compared with data of the pulsars. Contrary to pulsars and black holes, the low frequency QPOs of white dwarfs might be attributed to electromagnetic precession frequencies, deduced in this work. Predictions are compared with data of the dwarf nova VW Hyi.


our country's history. We also believe that patients with terminal conditions and terminal illness should have access to experimental treatment immediately that could potentially save their lives. People who are terminally ill should not have to go from country to country to seek a cure. I want to give them a chance right here at home. It's time for Congress to give these wonderful, incredible Americans the right to try. One of my greatest priorities is to reduce the price of prescription drugs. In many other countries, these drugs cost far less than what we pay in the United States. And it's very, very unfair. That is why I have directed my administration to make fixing the injustice of high drug prices one of my top priorities for the year. And prices will come down substantially. Watch. America has also finally turned the page on decades of unfair trade deals that sacrificed our prosperity and shipped away our companies, our jobs, and our wealth. Our nation has lost its wealth, but we're getting it back so fast. The era of economic surrender is totally over. From now on, we expect trading relationships to be fair and, very importantly, reciprocal. We will work to fix bad trade deals and negotiate new ones. And they'll be good ones, but they'll be fair. And we will protect American workers and American intellectual property through strong enforcement of our trade rules. As we rebuild our industries, it is also time to rebuild our crumbling infrastructure. America is a nation of builders. We built the Empire State Building in just one year. Isn't it a disgrace that it can now take 10 years just to get a minor permit approved for the building of a simple road? I am asking both parties to come together to give us safe, fast, reliable, and modern infrastructure that our economy needs and our people deserve. Tonight I'm calling on Congress to produce a bill that generates at least $1.5 trillion for the new infrastructure investment that our country so desperately needs. Every federal dollar should be leveraged by partnering with state and local governments and, where appropriate, tapping into private sector investment to permanently fix the infrastructure deficit. And we can do it. Any bill must also streamline the permitting and approval process, getting it down to no more than two years, and perhaps even one. Together, we can reclaim our great building heritage. We will build gleaming new roads, bridges, highways, railways, and waterways all across our land. And we will do it with American heart, American hands
